Cue summation enables perceptual grouping

In order to study how basic features interact in shape perception, subjects detected target figure presence and identified target figure shape in a combined 2-alternative forced-choice task. Target figures were embedded in Gabor random fields and were defined by feature contrast in spatial frequency, orientation, or both. Two figure classes were used: block figures, which could not be identified at low feature-contrast levels, and lozenge figures, which could be identified to a moderate degree. Results showed a substantial double-cue benefit for both figure classes in detection. In identification, however, a double-cue benefit was practically absent for blocks, whereas, for lozenges, cue summation proved to be much stronger than in detection. The finding that the way basic features interact is modulated by figure class and psychophysical task indicates involvement of 2 distinct perceptual mechanisms in shape perception. The 1st one highlights salient features and enables local grouping on an early feature-specific processing level. The 2nd one is higher level, serves form completion and grouping of salient contours into global shapes, and enables figure perception.     

Three ways to resist temptation: The independent contributions of executive attention, inhibitory control, and affect regulation to the impulse control of eating behavior

It is generally assumed that impulse control plays a major role in many areas of self-regulation such as eating behavior. However, the exact mechanisms that enable the control of impulsive determinants such as automatic affective reactions toward tempting stimuli are not well understood. “The present research investigated the separate moderator effects of three factors of impulse control, executive attention, inhibitory control, and affect regulation on the relationship between automatic affective reactions toward candy and subsequent candy consumption.” Results showed that all three factors reduced the influence of automatic affective reactions on eating behavior, indicating improved impulse control. Implications for self-regulation research are discussed.     

Interpersonal evaluation bias in borderline personality disorder

Background

The cognitive theory of personality disorders hypothesizes that the emotional dysregulation and interpersonal problems in individuals with borderline personality disorder (BPD) are, at least partially, caused by dysfunctional cognitive schemas. These schemas lead to biased evaluation of environmental and interpersonal stimuli.

Method

This study examined the interpersonal evaluations of individuals with BPD, depressive and healthy control participants with the thin-slice judgments paradigm. Participants were asked to evaluate six persons in six film clips, which showed these persons for 10 s, during which these persons entered a room and took a seat. Interpersonal style of the BPD group was investigated with the Inventory of Interpersonal Problems (IIP-C) questionnaire.

Results

Individuals with BPD judged the persons as being more negative and aggressive and less positive than the healthy participants, and more aggressive than the depressive individuals. In addition, individuals with BPD reported more extreme interpersonal behavior relative to the controls.

Conclusions

The findings indicate an aggressivistic evaluation bias and elevated levels of interpersonal problems in individuals with BPD as suggested in the cognitive theory.     

Challenges in the conceptualization of trait self-control as a psychological construct

Self-control is widely believed to be a valuable characteristic that contributes to leading a healthy, happy, and successful life through the effective pursuit of long-term goals. Yet, despite a prolific literature spanning decades, essential questions about the conceptual nature of trait self-control remain unanswered. Substantially different perspectives on the theoretical nature of (trait) self-control coexist side by side. We briefly review prominent views informing what trait self-control as a psychological construct is. On this basis, we identify four conceptual challenges that we think the field should address moving forward: (a) integrating theoretical notions, (b) addressing variability in individual goals, (c) acknowledging variability in dominant responses, and (d) anchoring trait self-control in a nomological network. We highlight why addressing these challenges is crucial for gaining a deeper understanding of trait self-control. We also suggest how theoretical conceptualizations of trait self-control might do so and the implications this would bear for measurement and interventions.     

Auditory Distraction by Meaningless Irrelevant Speech: A Developmental Study

The irrelevant sound effect (ISE) typically refers to a disruptive effect of a to‐be‐ignored sound in serial recall tasks, where lists of visually presented items (digits and letters) must be recalled in serial order. Although extensively studied in adults, studies on developmental aspects of the ISE are scarce. The present study aims to increase our understanding of developmental changes of auditory distraction in children beyond serial recall. Two tasks (i.e., word categorization and evaluation of simple mathematical equations) were designed to test retrieval from semantic memory. Proportion correct and reaction times (adjusted for speed–accuracy tradeoff) were measured in 8–9 and 12–13‐year‐olds. Results revealed a developmental change in the susceptibility to auditory distraction. Whereas older children were not affected by background sounds, younger children showed impairment in both proportion correct and adjusted reaction times. Overall, results suggest that attention distraction and immature attention control mechanisms contribute to ISEs in young children. Copyright © 2014 John Wiley & Sons, Ltd.     

Integration of internal and external facial features in 8- to 10-year-old children and adults

Investigation of whole-part and composite effects in 4- to 6-year-old children gave rise to claims that face perception is fully mature within the first decade of life (Crookes & McKone, 2009). However, only internal features were tested, and the role of external features was not addressed, although external features are highly relevant for holistic face perception (Sinha & Poggio, 1996; Axelrod & Yovel, 2010, 2011). In this study, 8- to 10-year-old children and adults performed a same–different matching task with faces and watches. In this task participants attended to either internal or external features. Holistic face perception was tested using a congruency paradigm, in which face and non-face stimuli either agreed or disagreed in both features (congruent contexts) or just in the attended ones (incongruent contexts). In both age groups, pronounced context congruency and inversion effects were found for faces, but not for watches. These findings indicate holistic feature integration for faces. While inversion effects were highly similar in both age groups, context congruency effects were stronger for children. Moreover, children's face matching performance was generally better when attending to external compared to internal features. Adults tended to perform better when attending to internal features. Our results indicate that both adults and 8- to 10-year-old children integrate external and internal facial features into holistic face representations. However, in children's face representations external features are much more relevant. These findings suggest that face perception is holistic but still not adult-like at the end of the first decade of life.     

Increased exposure and phonetic context help listeners recognize allophonic variants

This study examines the influence of increased exposure and phonetic context on the recognition of words that are produced with nasal flaps in American English (e.g., the word center produced as cenner). Previous work has shown that despite their high frequency of occurrence, words produced with nasal flaps are recognized more slowly and less accurately compared with canonical pronunciation variants produced with /nt/, which occur less frequently. We conducted two experiments in order to investigate how exposure and phonetic context influence this reported processing disadvantage for flapped variants. Experiment 1 demonstrated that the time to recognize flapped variants presented in isolation decreased over the course of the experiment, while accuracy increased. Experiment 2 replicated this finding and showed further that flapped variants that were presented in a casually produced sentence context were recognized faster compared with flapped variants presented in a carefully produced sentence context. Interestingly, the effect of context emerged only in late responses and was present only for flapped but not for canonical variants. Our results thus show that increased exposure and phonetic context help listeners recognize allophonic variants. This finding provides further support for the notion that listeners are flexible and adapt to phonetic variation in speech.     

Contextual modulation of prime response retrieval processes: Evidence from auditory negative priming

Contextual similarity between learning and test phase has been shown to be beneficial for memory retrieval. Negative priming is known to be caused by multiple processes; one of which is episodic retrieval. Therefore, the contextual similarity of prime and probe presentations should influence the size of the negative priming effect. This has been shown for the visual modality. In Experiment 1, an auditory four-alternative forced choice reaction time task was used to test the influence of prime-probe contextual similarity on negative priming and the processes underlying the modulation by context. The negative priming effect was larger when the auditory context was repeated than when it was changed from prime to probe. The modulation by context was exclusively caused by an increase in prime response retrieval errors in ignored repetition trials with context repetition, whereas repeating only the context but not the prime distractor did not lead to an increase in prime response retrieval. This exact pattern of results was replicated in Experiment 2. The findings suggest that contextual information is integrated with prime distractor and response information. Retrieval of the previous episode, including prime distractor, prime response, and context (event file), can be triggered when the former prime distractor is repeated, whereas a context cue alone does not retrieve the event file. This suggests an event file structure that is more complicated than its usually assumed binary structure.     

Regulatory focus and reliance on implicit preferences in consumption contexts

The present research tested the assumption that implicit preferences fit the eagerness of a promotion focus, but not the need for safe judgments and decisions of a prevention focus. In three studies, we assessed individual differences in implicit preferences for consumer goods and investigated their influence on self-regulatory behavior. In line with expectations, implicit preferences predicted choice intentions (Study 1), single and repeated choices between consumer goods (Study 2), and the amount of product consumption (Study 3) better for individuals in a promotion focus than in a prevention focus. The results were found with two different measures of implicit preferences.     

The notion of a recognitional concept and other confusions

The notion of a recognitional concept (RC) is stated precisely and shown to be unrelated to the proper notion of a perceptually based concept, defining of concept empiricism. More fundamentally, it is argued that the notion of an RC does not reflect a potentially sensible candidate theory of concepts at all and therefore ought to be abandoned from concept-theoretical discourse. In the later parts of the paper, it is shown independently of these points that Fodor’s attacks on RCs are in all central respects based on fallacies and confusions. Thus, even if the notion of an RC were one worth defending, it could not be threatened by Fodor’s attacks on it. Throughout the paper, I aim at clarification regarding the logical relations between various concept-theoretical options.
