Handling Follow-Ups Professionally: Strategies for Getting Replies When Facing Silence

This article discusses effective strategies for following up with contacts who have not responded to initial requests or messages. It begins by reviewing psychological research on factors that can influence response times, such as personality traits, cultural norms, and procrastination. It then provides guidelines for optimal timing of follow-ups based on priority level and contact type. Specific suggestions are offered for composing follow-up communications, including restating the original request, expressing the need for a response politely, acknowledging time constraints, and problem-solving rather than blaming. The article stresses the need for flexibility based on individual relationships and contexts. It offers examples of appropriately customizing follow-ups for scenarios like status updates, project kickoffs, and external partnerships. By understanding reasons for delays, timing follow-ups appropriately, and adapting language sensitively, leaders can productively follow through to obtain needed information and cooperation while preserving goodwill.

Deciphering the temporal dynamics of consumer decisions: the interplay of cognitive load and response correctness

This study delves into the impact of visual marketing stimuli on consumer response times, focusing on the complexity and subjectivity of the questions posed. Conducted in Slovakia, the research involved 40 participants (20 men and 20 women, aged 30 to 50 years), all holding university degrees in economics to ensure consistent decision-making experience. Participants were presented with visual stimuli representing four well-known FMCG brands. The stimuli included simple brand preference questions and complex evaluative judgments of offer efficiency. Response times were measured in milliseconds and analyzed using statistical methods, including the Mann-Whitney U test and one-way ANOVA. Results revealed that responses to simple stimuli averaged 1212 ms, while complex stimuli elicited slower responses, averaging 2504 ms. A significant difference was observed for “No” answers in the offer evaluation tasks, with correct “No” responses taking 3000 ms compared to 2297 ms for incorrect ones (p < 0.05), highlighting the cognitive load involved in accurate decision-making. These findings provide valuable insights into the cognitive processes driving consumer decision-making and contribute to the theoretical understanding of how question complexity and subjectivity influence response times.

Assessing the influence of emotional expressions on perceptual sensitivity to faces overcoming interocular suppression.

Detecting faces and identifying their emotional expressions are essential for social interaction. The importance of expressions has prompted suggestions that some emotionally relevant facial features may be processed unconsciously, and it has been further suggested that this unconscious processing yields preferential access to awareness. Evidence for such preferential access has predominantly come from reaction times in the breaking continuous flash suppression (bCFS) paradigm, which measures how long it takes different stimuli to overcome interocular suppression. For instance, it has been claimed that fearful expressions break through suppression faster than neutral expressions. However, in the bCFS procedure, observers can decide how much information they receive before committing to a report, so although their responses may reflect differential detection sensitivity, they may also be influenced by differences in decision criteria, stimulus identification, and response production processes. Here, we employ a procedure that directly measures sensitivity for both face detection and identification of facial expressions, using predefined exposure durations. We apply diverse psychophysical approaches-forced-choice localization, presence/absence detection, and staircase-based threshold measurement; across six experiments, we find that emotional expressions do not alter detection sensitivity to faces as they break through CFS. Our findings constrain the possible mechanisms underlying previous findings: faster reporting of emotional expressions' breakthrough into awareness is unlikely to be due to the presence of emotion affecting perceptual sensitivity; the source of such effects is likely to reside in one of the many other processes that influence response times.

Prolonged Processing Time for Manual and Vocal Responses in Parkinson Disease: A Psychological Refractory Period Paradigm Study

The purpose of this study was to examine a potential increased cognitive processing bottleneck within Parkinson disease (PD) by extending a previous overlapping task methodology. Additionally, this study extends previous overlapping task methodology in PD to examine the influence of modality (vocal vs. manual) on response delays in overlapping tasks in PD. This study used the psychological refractory period (PRP) paradigm (overlapping-task paradigm) to study processing limitations as participants complete two tasks that increasingly overlap in time. Three levels of temporal overlap of tasks were utilized to vary cognitive demands on manual and vocal response time tasks. Ten participants with PD (PwPD) and 12 participants without PD were included in this study. Participants with PD demonstrated response time delays across temporal overlap conditions (likely indicating motor deficits) along with a larger increase in response delays in the most overlapped, cognitively taxing condition (likely indicating longer central processing bottleneck). Additionally, modality did not influence response times differently in overlapping task conditions or within participant groups. An extension of previous overlapping task methodologies within a complex task was successful in demonstrating an increased central processing deficit across manual and vocal response delays in PD, regardless of modality of response.

Behavioral Responses to Body Position in Bees: The Interaction of Apis mellifera and Lithurgus littoralis in Prickly Pear Flowers.

The behavior of bees is modulated by the presence of other bees and potentially by the visual information transmitted by the different body positions of bees while visiting flowers. We tested whether bee body position promoted the attraction and/or antagonistic behavior of con- and hetero-specific bees that interacted on prickly pear flowers of Opuntia huajuapensis. To test this, we placed dummy model bees of Apis mellifera and the native Lithurgus littoralis in flowers in three common body positions: alert, feeding, and horizontal. The results showed that dummy model bees in feeding and horizontal body positions attracted A. mellifera bees, while the alert position attracted native male L. littoralis. Male L. littoralis bees spent more time attacking model bees in horizontal and alert positions. The position of dummy bees also influenced response times. Bees of A. mellifera responded fastest to L. littoralis in the alert and horizontal position, male L. littoralis responded fastest to con-specific bees in the alert and feeding position, and female L. littoralis responded fastest to A. mellifera bees in the feeding position. A. mellifera reacted fastest to their con-specific bees in the alert and horizontal body positions. Our results demonstrate, for the first time in bees, that the position of individuals on a floral resource provides important visual information that modulates bee behavior, and illuminates aspects that likely have implications for bees in access to floral resources.

A show about nothing: No-signal processes in systems factorial technology.

Systems Factorial Technology (SFT) is a popular framework for that has been used to investigate processing capacity across many psychological domains over the past 25+ years. To date, it had been assumed that no processing resources are used for sources in which no signal has been presented (i.e., in a location that can contain a signal but does not on a given trial). Hence, response times are purely driven by the signal-containing location or locations. This assumption is critical to the underlying mathematics of the capacity coefficient measure of SFT. In this article, we show that stimulus locations influence response times even when they contain no signal, and that this influence has repercussions for the interpretation of processing capacity under the SFT framework, particularly in conjunctive (AND) tasks-where positive responses require detection of signals in multiple locations. We propose a modification to the AND task requiring participants to fully identify both target locations on all trials. This modification allows a new coefficient to be derived. We apply the new coefficient to novel experimental data and resolve a previously reported empirical paradox, where observed capacity was limited in an OR detection task but super capacity in an AND detection task. Hence, previously reported differences in processing capacity between OR and AND task designs are likely to have been spurious. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Compound reading in German: Effects of constituent frequency and whole-word frequency in children and adults.

Current models of morphological processing differ in their assumptions about the recognition of compound words. The relative contribution of the first and second constituent and the whole-word remains unsolved. Particularly for beginning readers, the first constituent might have a privileged role attributable to more sequential decoding strategies. In a series of lexical decision experiments, the influence of constituent and whole-word frequencies on compound recognition was examined in German developing readers as well as adults. Results showed that whole-word and first constituent frequency interactively influenced response times in children. For adults, an effect of whole-word frequency only was obtained for the children's stimuli set, and noninteracting effects of whole-word frequency and first constituent frequency were found when using adult frequency measures. Together, the results suggest that developing readers already decompose compounds and that hybrid interactive models of morphological processing are most suitable to explain compound recognition across development. The applicability of amorphous models is also discussed. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Gaze Amplifies Value in Decision Making

When making decisions, people tend to choose the option they have looked at more. An unanswered question is how attention influences the choice process: whether it amplifies the subjective value of the looked-at option or instead adds a constant, value-independent bias. To address this, we examined choice data from six eye-tracking studies (Ns = 39, 44, 44, 36, 20, and 45, respectively) to characterize the interaction between value and gaze in the choice process. We found that the summed values of the options influenced response times in every data set and the gaze-choice correlation in most data sets, in line with an amplifying role of attention in the choice process. Our results suggest that this amplifying effect is more pronounced in tasks using large sets of familiar stimuli, compared with tasks using small sets of learned stimuli.

The impact of spoken action words on performance in a cross-modal oddball task.

In this study a cross-modal oddball task was employed to study the effect that words spoken either non-urgently or urgently would have on a digit categorization task and if women would exhibit greater behavioral inhibitory control. The words were unrelated to the task itself, but related to the action required to complete the task. Forty participants (21 women) conducted a computerized categorization task while exposed to a sinewave tone as a standard stimulus (75% of the trials) or a to-be ignored word (press, stop) spoken either non-urgently or urgently as unexpected auditory deviant stimulus (6.25% trials for each category). Urgent words had sharp intonation and an average fundamental frequency (F0) ranging from 191.9 (stop) to 204.6 (press) Hz. Non-urgent words had low intonation with average F0 ranging from 103.9.9 (stop) to 120.3 (press) Hz. As expected, deviant distraction and longer response times were found by exposure to the word stop, but deviant distraction was not found to be significant with the word press or due to intonation. While the results showed that women had in general longer reaction times, there were no gender differences found related to the deviant distraction caused by word or intonation. The present results do not support the hypothesis that women have greater behavioral inhibitory control, but there was evidence that the meaning of the word could influence response times.

Eye-Movement Evidence for Object-Based Attention in Chinese Reading

Is attention allocated to only one word or to multiple words at any given time during reading? The experiments reported here addressed this question using a novel paradigm inspired by classic findings on object-based attention. In Experiment 1, participants (N = 18) made lexical decisions about one of two spatially colocated Chinese words or nonwords. Our main finding was that only the attended word’s frequency influenced response times and accuracy. In Experiment 2, participants (N = 30) read target words embedded in two spatially colocated Chinese sentences. Our key finding here was that only target-word frequencies influenced looking times and fixation positions. These results support the hypothesis that words are attended in a strictly serial (and perhaps object-based) manner during reading. The theoretical implications of this conclusion are discussed in relation to models of eye-movement control during reading and the conceptualization of words as visual objects.

The detrimental effect of acute stress on response inhibition when exposed to acute stress: an event-related potential analysis.

Response inhibition as a core cognitive function plays a critical role in our daily activities. However, response inhibition can be easily altered when exposed to acute stress. The current study investigated how and whether or not acute stress impacted response inhibition and the underlying neural mechanism with behavioral and event-related potential methods. Healthy participants were assigned randomly to a modified Trier Social Stress Test as a stressor and a control condition. Then, event-related potentials were measured when participants performed a modified Go/No-Go task. In this task, participants were informed to make or withhold a response according to the colored frame of three different emotional pictures: negative, neutral, and positive. Increased negative effect in the stress condition compared with the control condition indicated a successful acute stress induction. The stress group showed significantly smaller frontal and central N2 mean difference waves, relatively less positive parietal P3 mean difference waves, and prolonged N2 and Nogo-P3 latency compared with the control group. In addition, the reaction time in 'Go' trials was correlated negatively with N2 and P3 difference waves in the stress group. Behaviorally, acute stress did not influence response times and miss rates of 'Go' trials as well as the rate of false alarms in 'No-Go' trials. These findings suggested that acute stress impaired conflict detection, monitoring processes, and response inhibition processes on the neural level without a behavioral performance deficit. These findings provide neural evidence for understanding how the dynamic processes of acute stress influence response inhibition.

Using Network Science Measures to Predict the Lexical Decision Performance of Adults Who Stutter.

Methods from network science have examined various aspects of language processing. Clinical populations may also benefit from these novel analyses. Phonological and lexical factors have been examined in adults who stutter (AWS) as potential contributing factors to stuttering, although differences reported are often subtle. We reexamined the performance of AWS and adults who do not stutter (AWNS) from a previously conducted lexical decision task in an attempt to determine if network science measures would provide additional insight into the phonological network of AWS beyond traditional psycholinguistic measures. Multiple regression was used to examine the influence of several traditional psycholinguistic measures as well as several new measures from network science on response times. AWS responded to low-frequency words more slowly than AWNS; responses for both groups were equivalent for high-frequency words. AWS responded to shorter words more slowly than AWNS, producing a reverse word-length effect. For the network measures, degree/neighborhood density and closeness centrality, but not whether a word was inside or outside the giant component, influenced response times similarly between groups. Network analyses suggest that multiple levels of the phonological network might influence phonological processing, not just the micro-level traditionally considered by mainstream psycholinguistics.

Distinctiveness effects in self-prioritization

ABSTRACTThe prioritization of self-relevant information has been shown in different selective-attention paradigms. Recently, in a new paradigm, formerly neutral material was associated with the self, a familiar person, or a neutral instance and, in a following matching task, the self-associated pairings were prioritized. To test whether this self-prioritization effect (SPE) might be explained by two different types of distinctiveness (distinctiveness due to self-relevance and distinctiveness due to differences in the stimulus material), we manipulated both types of distinctiveness asymmetries in this paradigm. Three experiments provide evidence that distinctiveness asymmetry due to semantic/grammatical differences influenced response times and signal detection rates. The data also show that the SPE remained reliable when controlling for the influence of grammatical distinctiveness. Thus, the results suggest that distinctiveness asymmetries do play a role in the matching paradigm, however, the SPE in the matching task is more than just the recoding of salient content.

When Perception Trumps Reality

Is semantic priming driven by the objective or perceived meaning of the priming stimulus? This question is relevant given that many studies suggest that the objective meaning of invisible stimuli can influence cognitive processes and behavior. In an experiment involving 66 participants, we tested how the perceived meaning of misperceived stimuli influenced response times. Stroop priming (i.e., longer response times for incongruent than for congruent prime-target pairs) was observed in trials in which the prime was correctly identified. However, reversed Stroop priming was observed when the prime stimulus was incorrectly identified. Even in trials in which participants reported no perception of the prime and identified the primes at close to chance level (i.e., trials that meet both subjective and objective definitions of being subliminal), Stroop priming corresponded to perceived congruency, not objective congruency. This result suggests that occasional weak percepts and mispercepts are intermixed with no percepts in conditions traditionally claimed to be subliminal, casting doubt on claims of subliminal priming made in previous reports.

Five shades of grey: Generalization in distractor-based retrieval of S-R episodes.

Binding theories assume that a stimulus and a response made to it are bound together, as in the case of the theory of event coding, in an event file (Hommel, Müsseler, Aschersleben, & Prinz, Behavioral and Brain Sciences, 24(05), 849-937, 2001). This binding occurs after even a single encounter with the stimulus and the response. Repeating any part of the event file will cause the entire file to be retrieved. However not only are relevant stimuli bound with responses but even irrelevant stimuli that co-occur with the target can be bound with the response, and repeating such a distractor will result in the event file being retrieved. Yet previous studies focused on retrieval effects due to repetition of the same distractor. In this experiment we analysed whether perceptually similar distractors still influence actions due to distractor-based retrieval of responses. Thirty-one participants responded to the shape of the stimulus while ignoring the luminance (5 different shades of grey). The similarity of the stimulus luminance between two consecutive trials influenced response times on response repetition trials. Response repetition effects were particularly facilitated with exact repetitions of the irrelevant feature luminance, and the strength of this effect diminished with increasing dissimilarity of luminance in a linear fashion. We conclude that response-retrieval effects due to distractor bindings follow the rules of generalization, as discussed in the conditioning literature.

The origins of age of acquisition and typicality effects: Semantic processing in aphasia and the ageing brain

Age of acquisition (AOA) has frequently been shown to influence response times and accuracy rates in word processing and constitutes a meaningful variable in aphasic language processing, while its origin in the language processing system is still under debate. To find out where AOA originates and whether and how it is related to another important psycholinguistic variable, namely semantic typicality (TYP), we studied healthy, elderly controls and semantically impaired individuals using semantic priming. For this purpose, we collected reaction times and accuracy rates as well as event-related potential data in an auditory category-member-verification task. The present results confirm a semantic origin of TYP, but question the same for AOA while favouring its origin at the phonology-semantics interface. The data are further interpreted in consideration of recent theories of ageing.

Does Number of Perceptions or Cross-Modal Auditory Cueing Influence Audiovisual Processing Speed?

What factors contribute to redundant target processing speed besides statistical facilitation? One possibility is that multiple percepts may drive these effects. Another, although not mutually exclusive hypothesis, is that cross-channel cueing from one modality to another may influence response times. We implemented an auditory-visual detection task using the sound-induced flash illusion to examine whether one or both of these possibilities contributes to changes in processing speed; we did so by examining the data of individual participants. Our results indicated shorter response times in several participants when multiple flashes were perceived in the standard sound-induced flash illusion, thereby replicating previous work in the literature. Additionally, we found evidence for faster responses in several participants when carrying out the same analysis in trials in which 1 beep was presented with 2 real flashes. Overall, our analysis indicates that some observers benefit from cross-modal facilitation, whereas others may benefit from a combination of cross-modal facilitation and increased perceptual judgments.

Automatic imitation? Imitative compatibility affects responses at high perceptual load.

Imitation involves matching the visual representation of another's action onto the observer's own motor program for that action. However, there has been some debate regarding the extent to which imitation is "automatic"-that is, occurs without attention. Participants performed a perceptual load task in which images of finger movements were presented as distractors. Responses to target letter stimuli were performed via finger movements that could be imitatively compatible (requiring the same finger movement) or incompatible with the distractor movements: In this common stimulus-response compatibility manipulation, the stimulus set comprises images of the response movements, producing an imitative compatibility effect. Attention to the distractor movements was manipulated by altering perceptual load through increasing the number of nontarget letter stimuli. If imitation requires attention, then at high perceptual load, imitative compatibility should not affect response times. In contrast, imitative compatibility influenced response times at high perceptual load, demonstrating that distractor movements were processed. However, the compatibility effect was reversed, suggesting that longer response times at high perceptual load tap into an inhibitory stage of distractor movement processing. A follow-up experiment manipulating temporal delay between targets and distractor movements supported this explanation. Further experiments confirmed that nonmovement distractor stimuli in the same configuration produced standard perceptual load effects and that results were not solely due to effector compatibility. These data suggest that imitation can occur without attention. (PsycINFO Database Record

Can adjustment to accented speech affect native language perception?

The human auditory system can quickly accommodate foreign-accented speech. However, the cognitive mechanisms underlying perceptual adjustment to non-native speech are not fully understood. The current study examined the perceptual consequences of adaptation toward foreign-accented speech on native language perception. Native English speakers performed an auditory shadowing task on word-length utterances in English. There were four blocks of trials. The words in the critical block (Block 3) were spoken by either a native American English speaker or a native Spanish speaker. The speaker in flanking blocks (Blocks 1–2, 4) was the same speaker, a different speaker with the same accent, or a different speaker with a different accent. Shadowing response times in the critical block were used to assess rapid perceptual adjustment and readjustment. Results showed that the nature of the preceding context influenced response times. Response times for items in the first quartile of the critical block were reliably slower when accent and talker changed than when accent and talker remained constant. These findings suggest that listeners develop perceptual expectations about ongoing speech, which when violated incur a short-term processing cost even for spoken words in the listeners’ native language.

Effect of stimulus intensity on response time distribution in multisensory integration

To increase the efficiency of multimodal user interfaces, one has to design them according to how multimodal features appear in the real world. Although spatial coincidence and matching intensity levels are important for perception, these factors received little attention in human–computer interaction studies. In our present study we aimed to map how spatial coincidence and different intensity levels influence response times. Sixteen participants performed a simple auditory localization task, where sounds were presented either alone or together with visual non-targets. We found that medium intensity visual stimuli facilitated responses to low intensity sounds. Analyses of response time distributions showed that intensity of target and non-target stimuli affected different parameters of the ex-Gaussian distribution. Our results suggest that multisensory integration and response facilitation may occur even if the non-target has low predictive power to the location of the target. Furthermore, we show that the parameters of the ex-Gaussian distribution can be related to distinct cognitive processes. The current results are potentially applicable in the design of an intelligent warning system that employs the user’s reaction time to adapt the warning signal for optimal results.
