The role of implicit motivation in hot and cold goal pursuit: Effects on goal progress, goal rumination, and emotional well-being

Two cross-sectional studies examined the role of implicit motivational needs in the association between personal goal pursuits and depressive symptoms and affect. Replicating and extending on findings reported by Brunstein et al. [Brunstein, J. C., Schultheiss, O. C., & Grässmann, R. (1998). Personal goals and emotional well-being: The moderating role of motive dispositions. Journal of Personality and Social Psychology, 75(2), 494–508], both studies provided evidence that goal progress significantly accounted for variations in depressive symptoms and happiness only in individuals with high levels of implicit motivation, but not in individuals low in implicit motivation. Moreover, in the absence of a strong sense of goal commitment, high levels of implicit motivation were associated with high goal progress in both studies and low levels of goal rumination in Study 2. These findings are interpreted within a dual-systems framework of motivation that distinguishes an implicit, intuitive, and hedonically driven from an explicit, effortful-analytical, and non-hedonic mode of goal pursuit.

Frames and brains: elicitation and control of response tendencies

Using magnetic resonance imaging, De Martino and colleagues investigated the neural signature that is associated with decisions between small sure amounts of money and large riskier amounts when the framing of the outcomes is varied. We interpret their results within a dual-system framework, in which different frames evoke distinct emotional responses that different individuals can suppress to various degrees. The study advances the integration of brain imaging results into cognitive theory.

Development of intuitive rules: Evaluating the application of the dual-system framework to understanding children’s intuitive reasoning

Theories of adult reasoning propose that reasoning consists of two functionally distinct systems that operate under entirely different mechanisms. This theoretical framework has been used to account for a wide range of phenomena, which now encompasses developmental research on reasoning and problem solving. We begin this review by contrasting three main dual-system theories of adult reasoning (Evans & Over, 1996; Sloman, 1996; Stanovich & West, 2000) with a well-established developmental account that also incorporates a dual-system framework (Brainerd & Reyna, 2001). We use developmental studies of the formation and application of intuitive rules in science and mathematics to evaluate the claims that these theories make. Overall, the evidence reviewed suggests that what is crucial to understanding how children reason is the saliency of the features that are presented within a task. By highlighting the importance of saliency as a way of understanding reasoning, we aim to provide clarity concerning the benefits and limitations of adopting a dual-system framework to account for evidence from developmental studies of intuitive reasoning.

Target detection and localization in visual search: A dual systems perspective

The dual visual systems framework (Milner & Goodale, 1995) was used to explore target detection and localization in visual search. Observers searched for a small patch of tilted bars against a dense background of upright bars. Target detection was performed along with two different localization tasks: direct pointing, designed to engage the dorsal stream, and indirect pointing, designed to engage the ventral stream. The results indicated that (1) target detection was influenced more by orientation differences in 3-D space than by 2-D pictorial differences, (2) target localization was more accurate for direct than for indirect pointing, and (3) there were performance costs for indirect localization when it followed target detection, but not for direct localization. This is consistent with direct localization's having greater dependence on the dorsal visual system than either target detection or indirect localization.
