A nonspatial sound modulates processing of visual distractors in a flanker task.

Successful navigation of information-rich, multimodal environments involves processing of both auditory and visual information. The extent to which information within each modality is processed varies due to many factors, but the influence of auditory stimuli on the processing of visual stimuli in these multimodal environments is not well understood. Previous research has shown that a preceding sound leads to decreased reaction times in visual tasks (Bertelson, 1967). The current study examines if a non-spatial, task-irrelevant sound additionally alters processing of visual distractors that flank a central target. We utilized a version of a flanker task in which participants responded to a central letter surrounded by two irrelevant flanker letters. When these flankers are associated with a conflicting response, a congruency effect occurs such that reaction time to the target is slowed (Eriksen & Eriksen, 1974). In two experiments using this task, results showed that a preceding tone caused general speeding of reaction time across flanker types, consistent with alerting. The tone also caused decreased variation in response time. Critically, the tone modulated the congruency effect, with a greater speeding for congruent flankers than for incongruent flankers. This suggests that the influence of flanker identity was more intense after tone presentation, consistent with a nonspatial sound increasing perceptual and/or response-association processing of flanking stimuli.

Exploring word memorability: How well do different word properties explain item free-recall probability?

What makes some words more memorable than others? Words can vary in many dimensions, and a variety of lexical, semantic, and affective properties have previously been associated with variability in recall performance. Free recall data were used from 147 participants across 20 experimental sessions from the Penn Electrophysiology of Encoding and Retrieval Study (PEERS) data set, across 1,638 words. Here, I consider how well 20 different word properties—across lexical, semantic, and affective dimensions—relate to free recall. Semantic dimensions, particularly animacy (better memory for living), usefulness (with respect to survival; better memory for useful), and size (better memory for larger) demonstrated the strongest relationships with recall probability. These key results were then examined and replicated in the free recall data from Lau, Goh, and Yap (Quarterly Journal of Experimental Psychology, 71, 2207–2222, 2018), which had 532 words and 116 participants. This comprehensive investigation of a variety of word memorability demonstrates that semantic and function-related psycholinguistic properties play an important role in verbal memory processes.

Absence of post-learning motor activity effects on memory for motor-related words

ABSTRACT Drawing a hypothesis from embodied theories of memory, van Dam, Rueschemeyer, Bekkering and Lindemann [(2013). Embodied grounding of memory: Toward the effects of motor execution on memory consolidation. The Quarterly Journal of Experimental Psychology, 66(12), 2310–2328] showed that recognition performance for action words could be modulated by actions performed during the retention interval, suggesting that motor actions during the retention interval affect memory consolidation. The results of 4 experiments from two different laboratories, designed to replicate and extend the van Dam et al. motor consolidation effect, are presented here. Two of the experiments (n = 30 and n = 44) exactly and independently replicated the experimental design and conditions of the original experiment. Yes/No recognition scores plus additional analysis of response times showed no motor consolidation effects. A third experiment (n = 44) manipulating type of processing during encoding also failed to find significant motor consolidation effects. Finally, a fourth experiment (n = 120) following a more standard reconsolidation paradigm, involving 24-hour intervals between learning and motor behaviour, and a 24-hour delayed test, also found null effects. The absence of effects of motor execution on memory consolidation is discussed in terms of the implications of these findings for the embodiment approach to cognition.

Monitoring comprehension in a foreign language: Trait or skill?

Success in higher education is highly dependent on students’ ability to efficiently read and comprehend large amounts of text in the speaker’s first/native language (L1) and also in a Foreign Language (FL). Good text comprehension requires readers to implement a variety of metacognitive processes in order to self-regulate understanding. However, most readers are inaccurate when monitoring their own comprehension level, in the native language. Several studies have investigated FL comprehension monitoring, mostly using self-report measures. The current study further explored the relationship between L1 and FL comprehension monitoring through the paradigm of ‘calibration of comprehension’ (Glenberg and Epstein in Journal of Experimental Psychology: Learning, Memory and Cognition, 11, 702-718, 1985). Specifically, 145 university students read texts in each language, answered comprehension questions and rated their confidence. Absolute and relative monitoring accuracy was calculated (bias and resolution, respectively) to study whether comprehension monitoring processes are trait-oriented (shared across languages and domains) or skill-oriented (dependent on language proficiency level). Results suggested that absolute monitoring accuracy is both trait and skill oriented. On the one hand, confidence ratings and bias were significantly correlated across L1, FL and a non-verbal task, suggesting trait-orientation. On the other hand, only individuals who were highly proficient in the FL shared their absolute monitoring skills between the languages, supporting the notion of a skill orientation. Relative monitoring was not associated across tasks or languages. Theoretical and practical implications for effective instruction and learning methods are discussed.

Understanding face identification through within-person variability in appearance: Introduction to a virtual special issue.

In the effort to determine the cognitive processes underlying the identification of faces, the dissimilarities between images of different people have long been studied. In contrast, the inherent variability between different images of the same face has either been treated as a nuisance variable that should be eliminated from psychological experiments or it has not been considered at all. Over the past decade, research efforts have increased substantially to demonstrate that this within-person variation is meaningful and can give insight into various processes of face identification, such as identity matching, face learning, and familiar face recognition. In this virtual special issue of the Quarterly Journal of Experimental Psychology, we explain the importance of within-person variability for face identification and bring together recent relevant articles published in the journal.

On the relative (un)importance of foveal vision during letter search in naturalistic scenes

The importance of high-acuity foveal vision to visual search can be assessed by denying foveal vision using the gaze-contingent Moving Mask technique. Foveal vision was necessary to attain normal performance when searching for a target letter in alphanumeric displays, Perception & Psychophysics, 62 (2000) 576–585. In contrast, foveal vision was not necessary to correctly locate and identify medium-sized target objects in natural scenes, Journal of Experimental Psychology: Human Perception and Performance, 40 (2014) 342–360. To explore these task differences, we used grayscale pictures of real-world scenes which included a target letter (Experiment 1: T, Experiment 2: T or L). To reduce between-scene variability with regard to target salience, we developed the Target Embedding Algorithm (T.E.A.) to place the letter in a location for which there was a median change in local contrast when inserting the letter into the scene. The presence or absence of foveal vision was crossed with four target sizes. In both experiments, search performance decreased for smaller targets, and was impaired when searching the scene without foveal vision. For correct trials, the process of target localization remained completely unimpaired by the foveal scotoma, but it took longer to accept the target. We reasoned that the size of the target may affect the importance of foveal vision to the task, but the present data remain ambiguous. In summary, the data highlight the importance of extrafoveal vision for target localization, and the importance of foveal vision for target verification during letter-in-scene search.

Category norms with a cross-sectional sample of adults in the United States: Consideration of cohort, age, and historical effects on semantic categories.

This paper describes normative data for newly collected exemplar responses to 70 semantic categories described in previous norming studies (Battig & Montague, Journal of Experimental Psychology, 80(3, pt.2): 1-46, 1969; Van Overschelde, Rawson, & Dunlosky, Journal of Memory and Language, 50(3): 289-335, 2004; Yoon et al., Psychology and Aging, 19(3), 379-393, 2004). These categories were presented to 246 young (18-39 years), middle (40-59 years), and older (60 years and older) English-speaking adults living in the United States who were asked to generate as many category exemplars as possible for each of the 70 categories. In order to understand differences in normative responses, we analyzed these responses a) between age groups within the current sample and b) in comparison to three previously published sets of norms. Experimental studies using such norms typically assume invariance of normative likelihoods across age and historical time. We replicate previous findings such that exemplar frequency correlations suggest moderate stability in generated category members between age groups and cohorts for many, but not all, categories. Further, analyses of rank-order correlations highlight that the traditional measure of typicality may not capture all aspects of typicality, namely that for some categories there is high consistency in the frequency of exemplars across age groups and/or norms, but the ordering of those exemplars differs significantly. We include a cluster analysis to aid in grouping categories based on relative stability across time, cohort, and age groups. These results emphasize the importance of maintaining and updating age-differentiated category norms.

Unifying psychological and biological approaches to understanding animal cognition.

This special issue has two main aims. The first aim is to broaden the scope of the Canadian Journal of Experimental Psychology. This aim is motivated by the simple fact that the journal's mandate includes comparative psychology, but many of the articles published in the journal are currently, and have been for some time, mainly human cognitive in nature. The second aim of this issue is one that we take very seriously, and that is to promote not only comparative cognition and cognitive ecology research but research from a diverse group of scientists. Although the global diversity in this special issue is not exhaustive, there is work highlighted from scientists at institutions in Canada, Germany, Italy, the Netherlands, Spain, the United Kingdom, and the United States.

Phonological priming effects with same-script primes and targets in the masked priming same-different task.

Norris, Kinoshita and colleagues (Kinoshita & Norris, Journal of Experimental Psychology: Learning, Memory, and Cognition, 35(1), 1-18, 2009; Journal of Experimental Psychology: General, 137(3), 434-455, 2010; Norris & Kinoshita, Quarterly Journal of Experimental Psychology, 63(1), 194-204, 2008) have suggested that the masked priming same-different task (SDT) is an excellent tool for studying the orthographic coding process because, in most circumstances, performance in that task is driven entirely by orthographic codes. More specifically, although evidence of phonological influences (i.e., phonological priming effects in the SDT) have been reported, Kinoshita, Gayed, and Norris (Journal of Experimental Psychology: Human Perception and Performance, 44(11), 1661-1671, 2018) have claimed that phonological priming does not arise in the SDT when the prime and target are written in the same script and the targets are words, the most typical experimental situation. Indeed, it does appear that no-one has yet reported phonological priming effects in such situations. The question of whether it is possible to observe phonological priming in such situations was more fully examined in the present experiments. Experiment 1 involved a masked priming SDT using Japanese Kanji script in which the primes and targets were homophonic but shared no characters. Experiment 2 was a parallel experiment using Chinese stimuli. In both experiments, phonological priming effects were observed for both one- and two-character words. These experiments indicate that, although the priming effects in masked priming SDTs undoubtedly have a strong orthographic basis, phonological codes also play a role even when the prime and (word) target are written in the same script.

CS as an effect: action-based evaluative conditioning depends on temporal contiguity

ABSTRACT In this study, we analysed Evaluative Conditioning (EC) with a recently introduced S-R paradigm [Blask et al., 2016. Doing is for feeling. Journal of Experimental Psychology: General, 145(10), 1263–1268], in which valence first transfers from an affective US to a response and then from this valence-laden response to a novel CS. Based on action control research, the CS in this procedure could be interpreted as an effect of the response. Hence, temporal contiguity of the valence-laden response and the CS should determine whether EC occurs. We tested this hypothesis in an experiment, in which we varied the time interval between the response and the subsequent CS. Results show that EC effects occurred only under conditions of high temporal contiguity thus supporting our assumptions. This finding sheds light on the processes underlying action-based EC in particular and evaluative learning in general.

Can mirror reading reverse the flow of time? Evidence from Japanese speakers

Accumulating evidence over the last two decades has established the causal role of a unidirectional orthography in shaping speakers’ mental representations of time. Casasanto and Bottini (Journal of Experimental Psychology: General, 143, 473-479, 2014) extended previous findings by showing that exposure to mirror-reversed orthography of speakers’ native language could completely redirect their mental timelines within minutes. However, the question of whether such a causal effect of writing direction on temporal cognition can be identified in speakers whose native languages adopt bidirectional orthographies remains underexplored in the literature. To address this issue, the present study focused on Japanese which uses bidirectional writing systems, one proceeding horizontally from left to right (HLR) and one vertically from top to bottom (VTB). Two experiments were performed, and the tasks asked participants to process standard/mirror orthography prime questions about time arranged horizontally or vertically, followed by horizontal or vertical arrays of pictorial target stimuli about temporal relations. Results demonstrated that Japanese speakers encoded passage of time into a top-to-bottom linear path commensurate with the VTB writing direction, but they did not align their mental representations of time with the HLR writing orientation. Accordingly, exposure to mirror-reversed bidirectional orthographies redirected Japanese speakers’ vertical but not horizontal space-time mappings. Theoretical implications concerning the causal effects of bidirectional orthographies and the generalizability of the representational flexibility of time maintained by Casasanto and Bottini (Journal of Experimental Psychology: General, 143, 473-479) are discussed.

A Critical Review of the Support for Variability as an Operant Dimension

There is abundant evidence that behavioral variability is more predominant when reinforcement is contingent on it than when it is not, and the interpretation of direct reinforcement of variability suggested by Page and Neuringer, Journal of Experimental Psychology: Animal Behavior Processes, 11(3), 429–452 (1985) has been widely accepted. Even so, trying to identify the underlying mechanisms in the emergence of stochastic-like variability in a variability contingency is intricate. There are several challenges to characterizing variability as directly reinforced, most notably because reinforcement traditionally has been found to produce repetitive responding, but also because directly reinforced variability does not always relate to independent variables the same way as more commonly studied repetitive responding does. The challenging findings in variability experiments are discussed, along with alternative hypotheses on how variability contingencies may engender the high variability that they undeniably do. We suggest that the typical increase in behavioral variability that is often demonstrated when reinforcement is contingent on it may be better explained in terms of a dynamic interaction of reinforcement and extinction working on several specific responses rather than as directly reinforced.

Negative emotional state modulates visual working memory in the late consolidation phase

ABSTRACT Although a considerable literature has grown up around the interactions between emotional state and visual working memory (VWM) performance, the mechanism underlying the impact of the negative emotional state on VWM remains unclear. The present study aimed to test whether the influence of emotional state is related to the early phase or late phase of VWM consolidation process. Across three experiments, we found that the negative emotional state did not affect VWM performance when the presentation time of stimuli was short. However, when the presentation time was long, the negative emotional state increased the VWM precision and reduced the VWM number. According to the two-phase model proposed by Ye et al. (2017. A two-phase model of resource allocation in visual working memory. Journal of Experimental Psychology: Learning, Memory, and Cognition, 43(10), 1557–1566. doi: 10.1037/xlm0000376), the results suggested that negative emotional state could affect the late phase of resource allocation in VWM consolidation process, but it has no impact on the early consolidation phase. The findings from this study make important contributions to the current literature regarding the emotional modulation of VWM.

Blurring past and present: Using false memory to better understand false hearing in young and older adults.

A number of recent studies have shown that older adults are more susceptible to context-based misperceptions in hearing (Rogers, Jacoby, & Sommers, Psychology and Aging, 27, 33-45, 2012; Sommers, Morton, & Rogers, Remembering: Attributions, Processes, and Control in Human Memory [Essays in Honor of Larry Jacoby], pp. 269-284, 2015) than are young adults. One explanation for these age-related increases in what we term false hearing is that older adults are less able than young individuals to inhibit a prepotent response favored by context. A similar explanation has been proposed for demonstrations of age-related increases in false memory (Jacoby, Bishara, Hessels, & Toth, Journal of Experimental Psychology: General, 134, 131-148, 2005). The present study was designed to compare susceptibility to false hearing and false memory in a group ofyoung and older adults. In Experiment 1, we replicated the findings of past studies demonstrating increased frequency of false hearing in older, relative to young, adults. In Experiment 2, we demonstrated older adults' increased susceptibility to false memory in the same sample. Importantly, we found that participants who were more prone to false hearing also tended to be more prone to false memory, supporting the idea that the two phenomena share a common mechanism. The results are discussed within the framework of a capture model, which differentiates between context-based responding resulting from failures of cognitive control and context-based guessing.

Examining the influence of different types of dynamic change in a visual search task.

It has been repeatedly demonstrated that when performing a visual search task, items can pop out of a display such that they are identified rapidly, independent of the number of distractors present. It has been less clear whether this type of pop-out is limited to static displays (e.g., images) or whether it can also occur in scenes containing movement, more akin to how we experience the real world. Recently, Jardine and Moore (Journal of Experimental Psychology: Human Perception and Performance, 42, 617-630, 2016) examined whether pop-out also occurs in displays consisting of dynamic motion - wherein items in the display rotated continuously until a critical frame that would elicit pop-out under static presentation conditions - and found that search was greatly impaired. It remains unclear, however, whether such impairment is exerted equivalently across all types of dynamic motions or if it is specific to orientation. In the present study, we replicate the original Jardine and Moore (Journal of Experimental Psychology: Human Perception and Performance, 42, 617-630, 2016) finding and extend this examination to another dimension - color change. We also explore whether search efficiency can be improved with dynamic context if aspects of the display become predictable. The results suggest that not all types of dynamic change impair search performance. Specifically, oddball color targets continue to pop out even when the items in the display are dynamic. Interestingly, adding predictable context did not aid search accuracy as expected, rather resulting in poorer performance. Taken together, the findings suggest that the influence of dynamic context on search performance is not absolute.

Introduction

Emotion-induced attentional bias: does it modulate the spatial Simon effect?

ABSTRACT Schlaghecken, F., Blagrove, E., Mantantzis, K., Maylor, E. A., & Watson, D. G. [(2017). Look on the bright side: Positivity bias modulates interference effects in the Simon task. Journal of Experimental Psychology: General, 146(6), 763–770] found larger spatial Simon effects for happy than sad faces. Unexpectedly, this enhancement was also observed for nonvalenced objects requiring the same response as happy faces. We examined whether the increase of the spatial Simon effect is location- or object-based. In Experiments 1 and 2, participants pressed a left/right key in response to a happy/sad face or a left-/right-pointing arrow. These stimuli appeared on the left/right side of fixation, with location being task-irrelevant. Consistent with Schlaghecken et al., the spatial Simon effect was numerically larger for happy than sad faces regardless of whether faces and arrows were presented in different blocks (Experiment 1) or intermixed within blocks (Experiment 2). However, the spatial Simon effect for arrows was not modulated by the faces’ emotional valence. Similar findings were observed with pointing hands in Experiment 3. Our results imply that attentional bias is associated with specific objects (e.g. faces) not locations.

Modeling test learning and dual-task dissociations

Much of cognitive psychology is premised on the distinction between automatic and intentional processes, but the distinction often remains vague in practice and alternative explanations are often not followed through. For example, Hendricks, Conway and Kellogg (Journal of Experimental Psychology: Learning, Memory, and Cognition, 39, 491–1500, 2013) found that dual tasks at training versus at test dissociated performance in two different artificial grammar learning tasks. This was taken as evidence for underlying automatic and intentional processes. In this article, a different explanation is considered based on test learning and similarity, where participants are assumed to update their knowledge at test. Contrasting formal memory models of test learning are implemented, and it is concluded that the models account for the relevant dissociations without assuming a distinction between automatic and intentional processes.

Individual differences in multiple object tracking, attentional cueing, and age account for variability in the capacity of audiovisual integration.

There has been a recent increase in individual differences research within the field of audiovisual perception (Spence & Squire, 2003, Current Biology, 13(13), R519-R521), and furthering the understanding of audiovisual integration capacity with an individual differences approach is an important facet within this line of research. Across four experiments, participants were asked to complete an audiovisual integration capacity task (cf. Van der Burg, Awh, & Olivers, 2013, Psychological Science, 24(3), 345-351; Wilbiks & Dyson, 2016, PLOS ONE 11(12), e0168304; 2018, Journal of Experimental Psychology: Human Perception and Performance, 44(6), 871-884), along with differing combinations of additional perceptual tasks. Experiment 1 employed a multiple object tracking task and a visual working memory task. Experiment 2 compared performance on the capacity task with that of the Attention Network Test. Experiment 3 examined participants' focus in space through a Navon task and vigilance through time. Having completed this exploratory work, in Experiment 4 we collected data again from the tasks that were found to correlate significantly across the first three experiments and entered them into a regression model to predict capacity. The current research provides a preliminary explanation of the vast individual differences seen in audiovisual integration capacity in previous research, showing that by considering an individual's multiple object tracking span, focus in space, and attentional factors, we can account for up to 34.3% of the observed variation in capacity. Future research should seek to examine higher-level differences between individuals that may contribute to audiovisual integration capacity, including neurodevelopmental and mental health differences.
