Domain‐specific impulsivity in school‐age children

Impulsivity is a salient individual difference in children with well‐established predictive validity for life outcomes. The current investigation proposes that impulsive behaviors vary systematically by domain. In a series of studies with ethnically and socioeconomically diverse samples of middle school students, we find that schoolwork‐related and interpersonal‐related impulsivity, as observed by teachers, parents, and the students themselves, are distinct, moderately correlated behavioral tendencies. Each demonstrates differentiated relationships with dimensions of childhood temperament, Big Five personality factors, and outcomes, such as report card grades. Implications for theoretical conceptions of impulsivity as well as for practical applications (e.g. domain‐specific interventions) are discussed.     

Impaired body but not face perception in patients with obsessive–compulsive disorder

Background. Empirical evidence involving the processing of social information by patients with obsessive–compulsive disorder (OCD) has been relatively scarce. Our study investigated the perceptual abilities of patients with OCD to recognize human faces and bodies. Method. Fifty‐four drug‐free or drug‐naïve patients with OCD and 42 healthy controls performed discrimination tasks consisting of four types of stimuli: two sets of faces that were manipulated with regard to configuration and features, human bodies, and chairs. The stimuli were presented in upright and upside‐down orientations. Results. Patients with OCD were significantly less accurate in discriminating pairs of bodily postures implying actions. However, we found no significant differences between patient and control groups in the ability to recognize faces and chairs. The inversion effects for bodies and faces were also comparable between the two groups. Conclusions. The current findings suggest that patients with OCD experience difficulty in perceiving static forms of bodily postures, but are able to adequately recognize human faces. Our data indicate a selective deficit in the perception of bodily postures in those with OCD and suggest that this deficit is probably not related to the abnormal configurational processing of social objects.     

Stability and Change in Domain‐specific Self‐esteem and Global Self‐esteem

A notable uptick of interest in the stability of self‐esteem has been observed over the past few years. Most researchers, however, have focused on unidimensional rather than multidimensional conceptualizations of self‐esteem. The paucity of empirical research is surprising given conflicting theoretical perspectives on the stability of self‐esteem. The goal of the present study was to thoroughly disentangle different conceptualizations of self‐esteem and test opposing classical theories on (i) the stability and (ii) the direction of mutual influence of these different forms of self‐esteem. We analysed two‐year longitudinal data from participants (N = 644 at T1, N = 241 at T2) with an average age of 47.0 years (SD = 12.4). Analyses using a latent variable approach revealed that the domains of self‐esteem were relatively stable in terms of rank order and mean levels. In fact, the size of the stability coefficients was comparable to that of other trait measures that have been reported in the literature and paralleled the stability observed for global self‐esteem. Results did not provide support for either top‐down or bottom‐up effects between domain‐specific and global self‐esteem. These findings have important theoretical and practical implications regarding the stability and development of self‐esteem in adulthood and advance the understanding of self‐esteem in personality theory. © 2018 European Association of Personality Psychology     

The affect heuristic,mortality salience,and risk: Domain‐specific effects of a natural disaster on risk‐benefit perception

We examine how affect and accessible thoughts following a major natural disaster influence everyday risk perception. A survey was conducted in the months following the 2004 south Asian Tsunami in a representative sample of the Swedish population (N = 733). Respondents rated their experienced affect as well as the perceived risk and benefits of various everyday decision domains. Affect influenced risk and benefit perception in a way that could be predicted from both the affect‐congruency and affect heuristic literatures (increased risk perception and stronger risk‐benefit correlations). However, in some decision domains, self‐regulation goals primed by the natural disaster predicted risk and benefit ratings. Together, these results show that affect, accessible thoughts and motivational states influence perceptions of risks and benefits.     

Repeated checking causes distrust in memory but not in attention and perception

Repeated checking to reduce memory distrust seems to be counterproductive: it increases memory distrust. Obsessive-compulsive (OC) patients tend to be uncertain about other cognitive domains as well, like attention and perception. In an experiment with 70 healthy participants, we tested whether perseverative checking induces distrust not only in memory, but also in attention and perception. Participants were administered a computer task in which they had to activate, deactivate, and check threat-irrelevant stimuli, and rate their confidence in memory, attention, and perception in a pre-test and post-test. In between these tests, the relevant checking group performed 20 checks of the same stimuli used in the pre- and post-test. The irrelevant checking group performed 20 checks of different stimuli. Although memory accuracy improved in both groups, repeated checking reduced confidence in memory, vividness, and detail in the relevant checking group, but not in the irrelevant checking group. A trend was found towards a decline in attentional confidence in the relevant checking group only. Perception was not affected by repetitive checking. A replication study revealed similar results of relevant checking on meta-memory, however, the trend for attentional distrust was not confirmed. The results suggest that perseveration may be domain specific, i.e., only the cognitive processes that are subject to perseveration are affected.     

Exploring Domain‐Specific Perfectionism

ABSTRACT The main objective of this research was to explore the extent to which perfectionism is a general personality trait across areas of functioning rather than a context‐specific trait. The study also explored the degree to which domain‐specific contingent self‐worth, perceived competence, and task value were associated with domain‐specific perfectionism. In a sample of 187 academically talented youth, a comparison of perfectionistic tendencies and cognitive appraisal processes in the school versus sports domain revealed significantly higher levels of perfectionism, perceptions of competence, task value, and contingent self‐worth in the school domain. Hierarchical regression analysis showed a significant main effect for contingencies of self‐worth on perfectionistic tendencies in both the school and sports domains. The results argue for the centrality of contingent self‐worth to the understanding of perfectionism.     

Impaired face recognition does not preclude intact whole face perception

We studied intact and impaired processes in a prosopagnosic patient (RP). In Experiment 1, RP showed an inversion superiority effect with both faces and objects, with better performance when stimuli were presented upside down than in normal upright orientation. In Experiment 2, we studied the effect of face configuration directly by comparing matching performance with normal vs. scrambled faces. RP was worse with normal than with scrambled faces, whereas normal controls showed an advantage of a good face context. In Experiment 3, RP showed interference from external face features on the evaluation of internal face features. These results indicate, first, that although RP is impaired in face recognition and face matching, he does still encode the whole face rather than relying completely on parts-based procedures. Second, RP has a deficit at the level of the configural processes involved in finding subtle differences between individual faces, as his performance is worse when presented with a normal face configuration than with scrambled or inverted faces.     

Resisting Everything Except Temptation: Evidence and an Explanation for Domain‐specific Impulsivity

We propose a model of impulsivity that predicts both domain‐general and domain‐specific variance in behaviours that produce short‐term gratification at the expense of long‐term goals and standards. Specifically, we posit that domain‐general impulsivity is explained by domain‐general self‐control strategies and resources, whereas domain‐specific impulsivity is explained by how tempting individuals find various impulsive behaviours, and to a lesser extent, in perceptions of their long‐term harm. Using a novel self‐report measure, factor analyses produced six (non‐exhaustive) domains of impulsive behaviour (Studies 1–2): work, interpersonal relationships, drugs, food, exercise and finances. Domain‐general self‐control explained 40% of the variance in domain‐general impulsive behaviour between individuals, r_effect = .71. Domain‐specific temptation (r_effect = .83) and perceived harm (r_effect = ?.26) explained 40% and 2% of the unique within‐individual variance in impulsive behaviour, respectively (59% together). In Study 3, we recruited individuals in special interest groups (e.g. procrastinators) to confirm that individuals who are especially tempted by behaviours in their target domain are not likely to be more tempted in non‐target domains.

Domain‐General and Domain‐Specific Creative‐Thinking Tests: Effects of Gender and Item Content on Test Performance

The study examined the effects of gender and item content of domain‐general and domain‐specific creative‐thinking tests on four subscale scores of creative‐thinking (fluency, flexibility, originality, and elaboration). Chinese tenth‐grade students (234 males and 244 females) participated in the study. Domain‐general creative thinking was measured by using two domain‐independent items—box and newspaper. Domain‐specific creative thinking was measured in the domain of history by two history‐specific items—school uniform and health food—that were part of lessons in modern Chinese history. Domain‐general creative‐thinking scores were not different across gender in any of the four subscales. In domain‐specific creative thinking, female students produced more responses (fluency) and more categories of ideas (flexibility), and more detailed answers (elaboration) on both items than did males. Gender difference was not found in originality. Item effects were significant in both general and specific creative‐thinking scores, with higher fluency, flexibility, and elaboration for the newspaper than the box item, and higher fluency, flexibility, originality, and elaboration for the school uniform than the health food item. The findings on both gender and item effects support the contention that personal interest and life experience influence the generation of creative solutions. The finding that gender did not differ in domain‐general creative‐thinking was expected, as the two general items (box and newspaper) are experienced similarly by both genders. As most of the creative‐thinking tests are influenced by individuals' experience beyond creative‐thinking ability, judicial evaluation and use of creative‐thinking scores are underscored.     

Late‐ but not early‐onset blindness impairs the development of audio‐haptic multisensory integration

Integrating different senses to reduce sensory uncertainty and increase perceptual precision can have an important compensatory function for individuals with visual impairment and blindness. However, how visual impairment and blindness impact the development of optimal multisensory integration in the remaining senses is currently unknown. Here we first examined how audio‐haptic integration develops and changes across the life span in 92 sighted (blindfolded) individuals between 7 and 70 years of age. We used a child‐friendly task in which participants had to discriminate different object sizes by touching them and/or listening to them. We assessed whether audio‐haptic performance resulted in a reduction of perceptual uncertainty compared to auditory‐only and haptic‐only performance as predicted by maximum‐likelihood estimation model. We then compared how this ability develops in 28 children and adults with different levels of visual experience, focussing on low‐vision individuals and blind individuals that lost their sight at different ages during development. Our results show that in sighted individuals, adult‐like audio‐haptic integration develops around 13–15 years of age, and remains stable until late adulthood. While early‐blind individuals, even at the youngest ages, integrate audio‐haptic information in an optimal fashion, late‐blind individuals do not. Optimal integration in low‐vision individuals follows a similar developmental trajectory as that of sighted individuals. These findings demonstrate that visual experience is not necessary for optimal audio‐haptic integration to emerge, but that consistency of sensory information across development is key for the functional outcome of optimal multisensory integration.     

Predicting global and topic‐specific certainty beliefs: Domain‐specificity and the role of the academic environment

Background. Epistemological beliefs are subjective theories of the structure and acquisition of knowledge. The instruments used to measure epistemological beliefs in educational psychology (see Duell & Schommer‐Aikins, 2001 ) typically consist of questionnaires tapping general, decontextualized beliefs about knowledge or knowledge acquisition in a specific field or in general. Aims. Using specific theories as stimuli, we determine the degree of topic‐specificity of certainty beliefs as well as the association between certainty beliefs and the learning environment. Sample. Participants were 662 upper secondary school students (Study 1) and 211 college students (Study 2). Method. A global instrument and a topic‐specific instrument were used to collect responses to up to 10 stimulus theories. Factor analysis, multiple regression analysis and multi‐level modelling were carried out. Results. Students' topic‐specific certainty beliefs varied markedly across the stimulus theories. Furthermore, students in different academic environments differed more strongly on global certainty beliefs than on topic‐specific certainty beliefs, and global certainty beliefs were only loosely connected to topic‐specific certainty beliefs. Conclusion. Researchers should critically assess the validity of decontextualized global questionnaires for assessing certainty beliefs. If possible, global measures should be complemented by topic‐specific measures.     

Domain‐specific and domain‐general precursors of mathematical achievement: A longitudinal study from kindergarten to first grade

Background. Many contributing factors, both domain specific and domain general, influence children's performance in school achievement. Aims. This research aims to verify the importance of kindergarten measures of cognitive abilities and numerical competence in the role of predicting mathematical school achievement at the end of first grade. Sample and Methods. A total of 70 children (38 females and 32 males) took part in the study. We tested the children at the beginning of their last year of kindergarten (time 1) on the following cognitive abilities: IQ, phonology, counting skills, verbal short‐term memory, visuo‐spatial short‐term memory, working memory, and processing speed. Then, we tested the same children at end of their last year of kindergarten (time 2) on a measure of numerical competence and at the end of their first year of primary school (time 3) on a test of math achievement. Results. Path analysis models revealed the direct influence of working memory and processing speed on predicting numerical competence in pre‐schoolers and the influence of processing speed and verbal IQ on predicting math achievement in first graders. Moreover, this study found a direct link between numerical competence and math achievement. Conclusions. Both domain‐specific and domain‐general factors contribute to determining math achievement at the end of first grade.     

Event‐related potentials reveal linguistic suppression effect but not enhancement effect on categorical perception of color

The present study used the event‐related potential technique to investigate the nature of linguistic effect on color perception. Four types of stimuli based on hue differences between a target color and a preceding color were used: zero hue step within‐category color (0‐WC); one hue step within‐category color (1‐WC); one hue step between‐category color (1‐BC); and two hue step between‐category color (2‐BC). The ERP results showed no significant effect of stimulus type in the 100‐200 ms time window. However, in the 200–350 ms time window, ERP responses to 1‐WC target color overlapped with that to 0‐WC target color for right visual field (RVF) but not left visual field (LVF) presentation. For the 1‐BC condition, ERP amplitudes were comparable in the two visual fields, both being significantly different from the 0‐WC condition. The 2‐BC condition showed the same pattern as the 1‐BC condition. These results suggest that the categorical perception of color in RVF is due to linguistic suppression on within‐category color discrimination but not between‐category color enhancement, and that the effect is independent of early perceptual processes.     

Recognising faces but not traits: Accurate personality judgment from faces is unrelated to superior face memory

It is suggested that accurate personality judgments of faces are driven by a morphological ‘kernel of truth’ from face shape. We hypothesised that this relationship could lead to those with better face identification ability being better at personality judgments. We investigated the relationship between face memory, face matching, Big Five personality traits, and accuracy in recognising Big Five personality traits from 50 photographs of unknown faces. In our sample (n = 792) there was overall good (but varying) face memory and personality judgment accuracy. However, there was convincing evidence that these two skills do not correlate (all r < 0.06). We also replicate the known relationship between extraversion and face memory ability in the largest sample to date.     

Language‐specific stress perception by 9‐month‐old French and Spanish infants

During the first year of life, infants begin to have difficulties perceiving non‐native vowel and consonant contrasts, thus adapting their perception to the phonetic categories of the target language. In this paper, we examine the perception of a non‐segmental feature, i.e. stress. Previous research with adults has shown that speakers of French (a language with fixed stress) have great difficulties in perceiving stress contrasts ( Dupoux, Pallier, Sebastián & Mehler, 1997 ), whereas speakers of Spanish (a language with lexically contrastive stress) perceive these contrasts as accurately as segmental contrasts. We show that language‐specific differences in the perception of stress likewise arise during the first year of life. Specifically, 9‐month‐old Spanish infants successfully distinguish between stress‐initial and stress‐final pseudo‐words, while French infants of this age show no sign of discrimination. In a second experiment using multiple tokens of a single pseudo‐word, French infants of the same age successfully discriminate between the two stress patterns, showing that they are able to perceive the acoustic correlates of stress. Their failure to discriminate stress patterns in the first experiment thus reflects an inability to process stress at an abstract, phonological level.     

Two‐year‐olds use adults' but not peers' points

In the current study, 24‐ to 27‐month‐old children (N = 37) used pointing gestures in a cooperative object choice task with either peer or adult partners. When indicating the location of a hidden toy, children pointed equally accurately for adult and peer partners but more often for adult partners. When choosing from one of three hiding places, children used adults’ pointing to find a hidden toy significantly more often than they used peers’. In interaction with peers, children's choice behavior was at chance level. These results suggest that toddlers ascribe informative value to adults’ but not peers’ pointing gestures, and highlight the role of children's social expectations in their communicative development.     

TMS to the “occipital face area” affects recognition but not categorization of faces

The human cortical system for face perception is comprised of a network of connected regions including the middle fusiform gyrus (“fusiform face area” or FFA), the inferior occipital cortex (“occipital face area” or OFA), and the superior temporal sulcus. The traditional hierarchical feedforward model of visual processing suggests information flows from early visual cortex to the OFA for initial face feature analysis to higher order regions including the FFA for identity recognition. However, patient data suggest an alternative model. Patients with acquired prosopagnosia, an inability to visually recognize faces, have been documented with lesions to the OFA but who nevertheless show face-selective activation in the FFA. Moreover, their ability to categorize faces remains intact. This suggests that the FFA is not solely responsible for face recognition and the network is not strictly hierarchical, but may be organized in a reverse hierarchical fashion. We used transcranial magnetic stimulation (TMS) to temporarily disrupt processing in the OFA in neurologically-intact individuals and found participants’ ability to categorize intact versus scrambled faces was unaffected, however face identity discrimination was significantly impaired. This suggests that face categorization but not recognition can occur without the “earlier” OFA being online and indicates that “lower level” face category processing may be assumed by other intact face network regions such as the FFA. These results are consistent with the patient data and support a non-hierarchical, global-to-local model with re-entrant connections between the OFA and other face processing areas.     

I know your face but not where I saw you: Context memory is impaired for other-race faces

People are more likely to falsely identify a face of another race than a face of their own race. When witnesses make identifications, they often need to remember where they have previously encountered a face. Failure to remember the context of an encounter can result in unconscious transference and lead to misidentifications. Forty-five White participants were shown White and Black faces, each presented on one of five backgrounds. The participants had to identify these faces in an old/new recognition test. If participants stated that they had seen a face, they had to identify the context in which the face had originally appeared. Participants made more context errors with Black faces than with White faces. This shows that the own-race bias extends to context memory.     

Ageing affects conceptual but not perceptual memory processes

Whereas age effects commonly occur in tests of explicit memory, tests of implicit memory often show age invariance. In two experiments, the traditional confound between test type (implicit vs explicit) and retrieval process (conceptually driven vs perceptually driven) was removed by using conceptually driven and perceptually driven tests of both implicit and explicit memory. Experiment 1 revealed a significant age effect for conceptually driven retrieval and no age effect for perceptually driven retrieval, regardless of the type of memory being measured. Experiment 2 highlighted a difference between the two age groups in their ability to utilise semantic encoding in a nominally perceptually driven explicit memory test. The paper concludes that although perceptually driven processing is stable over age, particular care must be taken to minimise contamination from conceptually driven retrieval processes in such investigations.
