Structural aspects of face recognition and the other-race effect

The other-race effect was examined in a series of experiments and simulations that looked at the relationships among observer ratings of typicality, familiarity, attractiveness, memorability, and the performance variables ofd’ and criterion. Experiment 1 replicated the other-race effect with our Caucasian and Japanese stimuli for both Caucasian and Asian observers. In Experiment 2, we collected ratings from Caucasian observers on the faces used in the recognition task. A Varimax-rotated principal components analysis on the rating and performance data for the Caucasian faces replicated Vokey and Read’s (1992) finding that typicality is composed of two orthogonal components, dissociable via their independent relationships to: (1) attractiveness and familiarity ratings and (2) memorahility ratings. For Japanese faces, however, we fond that typicality was related only to memorahility. Where performance measures were concerned, two additional principal components dominated by criterion and byd’ emerged for Caucasian faces. For the Japanese faces, however, the performance measures ofd’ and criterion merged into a single component that represented a second component of typicality, one orthogonal to thememorability-dominated component. A measure offace representation quality extracted from an autoassociative neural network trained with a majority of Caucasian faces and a minority of Japanese faces was incorporated into the principal components analysis. For both Caucasian and Japanese faces, the neural network measure related both to memorability ratings and to human accuracy measures. Combined, the human data and simulation results indicate that the memorahility component of typicality may be related to small, local, distinctive features, whereas the attractiveness/familiarity component may be more related to the global, shape-based properties of the face.     

Seven‐ to 9‐month‐old infants use facial expressions to interpret others' actions

In Study 1, 7‐month‐old infants (N = 58) looked reliably more at an adult's face when she playfully pulled a toy away from them compared with when she simply handed them the toy. In Study 2, 7‐ and 9‐month‐old infants (N = 36) interacted with an adult who played a teasing game and then held a neutral or happy facial expression. Compared with a baseline in which infants looked equally to both expressions, after the tease, infants looked longer at the neutral compared with the happy expression. By 7 months, infants may use facial expressions to disambiguate others' actions.     

Psychological Factors Associated with a Better Quality of Life Following Head-Up Tilt Testing

Quality of life (QoL) is reduced in patients with recurrent vasovagal (VVS) or unexplained syncope (US). Little is known concerning the natural evolution of QoL following diagnosis. Psychological factors contributing to QoL improvement, such as psychological distress and self-efficacy remain to be explored. The objective of this study is to examine whether QoL changes 2 months and 6 months following head-up tilt (HUT) testing as well as to determine whether psychological factors are predictive of changes in QoL. Seventy-three patients undergoing HUT for recurrent syncope were interviewed 1 month before as well as 2 months and 6 months following HUT, using semi-structured interviews and questionnaires. Pre-HUT QoL was significantly worse than at the 2-month (p = 0.000) and 6-month follow-ups (p = 0.000). Psychological distress at baseline was associated with worse QoL 2 months post-HUT (Beta = .280; p = .024), independently of socio-demographic and clinical factors. Improved self-efficacy at follow-up predicted improvements in QoL (Beta = −.186; p = .023). Two and 6 months post-HUT, QoL is mproved in patients with recurrent syncope. Better QoL is predicted by low psychological distress and a heightened sense of self-efficacy following HUT. Strategies for enhancing self-efficacy and reducing psychological distress could be an efficient way to promote QoL in patients suffering from recurrent syncope.     

High dose alcohol consumption predicts less reduction in post-traumatic stress symptoms after a campus mass shooting

Background: Recognizing that alcohol might affect subsequent processing of trauma-related information, this study examined whether high dose alcohol consumption (HDAC) following a campus mass shooting affected the relation between shooting exposure and post-traumatic stress symptoms (PTSS).

Methods: Female participants (N?=?691) recorded levels of physical exposure to the shooting event, alcohol use, and PTSS 1 month following the shooting event and 8 months later.

Results: No evidence was found to suggest that pre-shooting HDAC moderated the relationship between trauma exposure and PTSS 1 month following the shooting. HDAC in the month following the shooting predicted less resolution of PTSS 8 months later. Specifically, at higher (but not lower) levels of HDAC, shooting exposure was associated with less reduction in PTSS from 1 to 8 months post-trauma. Several alternate explanations were ruled out.

Conclusions: Less reduction in PTSS seems to occur at high levels of both shooting exposure and HDAC. Theoretical implications and directions for future research are discussed.     

Predictors of distress following an acute stroke: Disability,control cognitions,and satisfaction with care

Abstract

Whilst clinical predictors of distress following acute stroke have been identified (e.g., lesion site), this study hypothesised that greater prediction would be achieved by addressing individual differences in patients' cognitions (e.g., perceived control, satisfaction with care, recovery confidence) and coping responses. We examined these relationships in a longitudinal study of 71 survivors of acute stroke. Measures were collected at three time points: 10-20 days after the stroke, and one month and six months after hospital discharge. Stepwise multiple regression analyses were performed using only significant bivariate correlates and where the dependent variables were residualised scores which controlled for baseline levels of anxiety and depression. Satisfaction with treatment and confidence in recovery at one month predicted anxiety outcome at six months, and satisfaction with advice and confidence in recovery at one month predicted depression outcome at six months. These results offer tentative suggestions for interventions targeting patient cognitions and improving patient satisfaction.     

Enhancing children's event recall after long delays

The effects of context reinstatement as means of enhancing 5‐ and 6‐year‐old children's event memory in repeated interviews after a 6‐month delay were examined. Children were interviewed immediately after the event (baseline interview) and twice at a 6‐month delay, with 24 hours between interviews. The first 6‐month interview was conducted in a perfect‐context reinstatement (n = 15), imperfect‐context reinstatement (n = 16), or no‐context reinstatement (n = 15) condition. The second 6‐month interview was conducted 24 hours later with no‐context reinstatement for all children. Context reinstatement attenuated the effects of delay on recall. The accuracy of the details reported was greater in the perfect‐context compared to the imperfect‐context and no‐context conditions. Details repeated between the immediate‐baseline interview and in the first 6‐month interview were more accurate than details repeated between the first and second 6‐month interview. There was no increase in recall (hypermnesia) across the first and second 6‐month interviews in any condition. Practical implications of these findings are discussed.

Follow-up of victims of one terrorist attack in Israel: ASD, PTSD and the perceived threat of Iraqi missile attacks

The first aim of the study was to examine the relationships between acute stress reactions and post-traumatic reactions following exposure to a terrorist attack. The second was to examine whether exposure to a terrorist attack increases the perceived threat and fear of renewed Iraqi missile attacks. Data were collected at two points in time: during the first month after the exposure to a terrorist attack (N = 54), and four months later (N = 44). Twenty-four percent of the exposed group had acute stress disorder (ASD), and a similar percentage had PTSD. Among participants who had ASD, the chances of developing PTSD were three times greater than among those who had never experienced ASD. Among participants who had been exposed to a terrorist attack and developed PTSD, the perceived threat of an Iraqi missile attack was greater than among those who had been exposed to a terrorist attack but did not develop PTSD, or among the participants in the control group. The discussion deals with the findings in light of the current controversy regarding ASD and the current situation in Israel.     

Logical Metonymy Resolution in a Words‐as‐Cues Framework: Evidence From Self‐Paced Reading and Probe Recognition

Logical metonymy resolution (begin a book → begin writing a book) has traditionally been explained either through complex lexical entries (qualia structures) or through the integration of the implicit event via post‐lexical access to world knowledge. We propose that recent work within the words‐as‐cues paradigm can provide a more dynamic model of logical metonymy, accounting for early and dynamic integration of complex event information depending on previous contextual cues (agent and patient). We first present a self‐paced reading experiment on German subordinate sentences, where metonymic sentences and their paraphrased version differ only in the presence or absence of the clause‐final target verb (Der Konditor begann die Glasur → Der Konditor begann, die Glasur spreading the icing). Longer reading times at the target verb position in a high‐typicality condition (baker + icing → spread ) suggest that we make use of knowledge activated by lexical cues to build expectations about events. The early and dynamic integration of event knowledge in metonymy interpretation is bolstered by further evidence from a second experiment using the probe recognition paradigm. Presenting covert events as probes following a high‐typicality or a low‐typicality metonymic sentence (Der Konditor begann die Glasur → SPREAD ), we obtain an analogous effect of typicality at 100 ms interstimulus interval.     

The benefits of self-compassion and optimism exercises for individuals vulnerable to depression

The effectiveness of two online exercises intended to help individuals experience (1) self-compassion (n?=?63) and (2) optimism (n?=?55) were compared to a control intervention where participants wrote about an early memory (n?=?70). A battery of tests was completed at 1 week following the exercise period, and at 1-, 3-, and 6-month follow-ups. Both active interventions resulted in significant increases in happiness observable at 6 months and significant decreases in depression sustained up to 3 months. The interventions were examined in relationship to dependency and self-criticism, both related to vulnerability to depression. Individuals high in self-criticism became happier at 1 week and at 1 month in the optimism condition in the repeated measures analysis. A sensitivity test using multi-level modeling failed to replicate this effect. More mature levels of dependence (connectedness) were related to improvements in mood up to 6 months in the self-compassion condition. This study suggests that different personality orientations may show greater gains from particular types of positive psychology interventions.     

Health Related Quality of Life After Percutaneous Coronary Revascularisation in Patients with Previous Coronary Artery Bypass Grafts: A Two-Year Follow Up Study

Percutaneous coronary revascularisation [PCR] improves angina and health related quality of life [HRQOL] compared to standard medical therapy. It is unknown whether PCR has the same benefits for patients with a history of CABG. Over a period of 5 years, we assessed HRQOL of patients undergoing PCR using Part 1 of the Nottingham Health Profile [NHP] at baseline 3, 12 and 24 months. We compared HRQOL after PCR in 255 patients with CABG to 2680 without. There were more males [81.1% v 69.6% p = 0.002] and older patients [mean age 60.1 years v. 58.0 p = 0.03] in CABG group. Perceived HRQOL improved at 24 months for pain, energy and emotional reaction but the improvement was less in the CABG group. However, mean NHP scores at 24 months for those with CABG had returned to baseline levels for sleep [34.9] and for physical function was worse than at baseline [22.0 vs 30.7]. This relationship persisted after adjustment for male sex, history of previous MI and coronary stent usage. Patients with previous CABG had less improvement in HRQOL after PCR. Further work is needed to assess the benefits and cost effectiveness of PCR in these patients.     

Real‐world word learning: Exploring children's developing semantic representations of a science term

Assessments of lexical acquisition are often limited to preschool children on forced‐choice comprehension measures. This study assessed the nature of the understandings 30 school‐age children (mean age = 6;7) acquired about the science term eclipse following a naturalistic exposure to a solar eclipse. The knowledge children acquired about eclipses and a control term comet was assessed at three points in time (baseline‐test, 2‐week post‐test and 5‐month post‐test) using a range of assessment tasks (multiple‐choice comprehension, picture‐naming, drawing and a model solar system manipulation task). Children's knowledge at the baseline‐test and 2‐week post‐test was compared with that of 15 adult controls. The analysis focused on the range of knowledge children acquired about eclipses and the relationships between aspects of knowledge they acquired. We found that children acquired extensive knowledge about eclipses, but not comets. At the 2‐week post‐test, the majority of children were able to produce the term eclipse and provided evidence of accurate comprehension and wider conceptual knowledge about solar eclipses, which was retained at the 5‐month post‐test. Further, children's ability to produce the term was related to their acquisition of ‘rich’ semantic and conceptual knowledge.     

The effect of IQ level on the degree of cognitive deterioration experienced during acute hypoglycemia in normal humans

Acute hypoglycemia provokes a deterioration in cognitive function both in normal individuals and patients with Type 1 diabetes. A large interindividual variation is observed in the magnitude of the cognitive dysfunction observed during hypoglycemia, the reasons for which are not apparent. This study examines whether IQ level exerts a differential effect on the impairment of cognitive performance induced during acute hypoglycemia. Twenty-four nondiabetic participants were divided into high and average IQ groups according to their results on the Alice Heim 4 test and the National Adult Reading Test. Cognitive function was assessed during hypoglycemia using the following cognitive test battery: Paced Auditory Serial Addition Test (PASAT), Rapid Visual Information Processing (RVIP), Trail-Making B (TMB), Digit Symbol Substitution Test (DSST), and Four-Choice Reaction Time (CRT). In Condition A (the placebo condition), the participants' blood glucose was maintained at 4.5 mmol/1 throughout. On two occasions (Conditions B and C), the blood glucose was stabilized at 4.5 mmol/1 for 30 min, lowered to 2.5 mmol/1 (hypoglycemia) for 60 min, and restored to 4.5 mmol/1 for 30 min. Under each condition, the cognitive test battery was performed immediately after stabilization of blood glucose at 4.5 mmol/1, and the battery was repeated as follows: Condition A—after a further 40 min of euglycemia; Condition B—after 5 min of hypoglycemia; Condition C—after 40 min of hypoglycemia. Multivariate analysis of variance demonstrated a detoriation in cognitive performance as a result of hypoglycemia irrespective of IQ group (p< .005). Acute hypoglycemia induced a significant deterioration in cognitive function in all tests except TMB (p< .05). No overall effect of IQ on deterioration in cognitive performance could be ascertained, although univariate analysis of variance revealed an IQ effect on two of the test: The avergae IQ group deteriorated significantly less than the higher IQ group during hypoglycemia in the 4-s PASAT task (p = .03) and tended to have higher false alarm rates in the RVIP (p = .06). In conclusion, individuals with a higher IQ do not appear to be protected from tge adverse effects of acute hypoglycemia on cognitive function.     

Effects of attentional demand,cue typicality,and priming on an event‐based prospective memory task

The main purpose of this experiment was to examine the independent and interactive effects of three variables—attentional demand, cue typicality, and priming—on an event‐based prospective memory task. High attentional demand was expected to lower performance, but cue typicality and priming were expected to improve performance. The prospective memory task entailed writing an ‘X’ after hearing items from four semantic categories (e.g. birds), while performing a free‐association task. Results showed the predicted effects of attentional demand and typicality. Priming did not affect overall prospective memory performance but, as predicted, improved performance under conditions of high attentional demand with a typical cue. Overall, these results show the importance of cue and capacity variables, but they also support the value of examining how different variables in the prospective memory task can interact in affecting performance.

Trajectories of Postpartum Maternal Depressive Symptoms and Children’s Social Skills

The vast majority of new mothers experience at least some depressive symptoms. Postpartum maternal depressive symptoms can greatly influence children’s outcomes (e.g., emotional, cognitive, language, and social development). However, there have been relatively few longitudinal studies of how maternal depressive symptoms may influence children’s social skills. The current study (n = 1363) examined the trajectory of maternal depressive symptoms (from 1 month to 36 months) and whether maternal depressive symptoms at 1 month postpartum and the change in symptoms over time (from 1 month to 3 years) predicted children’s parent- and teacher-rated social skills when they were 4.5 and 6.0 years old. A growth curve model indicated that, on average, maternal depressive symptoms declined over time in a nonlinear fashion. Further analyses indicated that after controlling for five demographic factors (child sex, family income, maternal age, mother’s marital status, and maternal education), initial maternal depressive symptoms significantly predicted children’s social skills as reported by mothers. The results support the notion that maternal depressive symptoms during children’s infancy can have long-term associations with children’s social skills. In addition, the results emphasize the importance of intervention and prevention efforts targeting maternal depressive symptoms during infancy, beginning immediately postpartum.     

The Ontogeny of Long‐Term Retention During the Second Year of Life

Developmental changes in retention were assessed in two experiments with 18‐ and 24‐month‐old infants. In both experiments, infants were tested in a deferred imitation paradigm. In Experiment 1, independent groups of infants were tested either immediately or after delays of 1, 14, 28 or 56 days. There was no age‐related difference in the spontaneous production of target actions (baseline) or in immediate imitation. There were age‐related changes in retention after longer delays. Eighteen‐month‐olds exhibited retention for 14 days and 24‐month‐olds exhibited retention for at least 56 days. In Experiment 2, the maximum duration of retention by 24‐month‐olds was assessed. Independent groups of infants were tested after 3 or 6 months. Infants exhibited some evidence of retention after 3 months; however, forgetting was complete after 6 months.     

EVALUATION OF AN INPATIENT PROGRAM AIMED AT PREPARING “HARD-TO-PLACE” CHRONICALLY MENTALLY ILL FOR THE COMMUNITY

A program designed to prepare long-stay “hard-to-place” psychiatric inpatients for successful community placement was evaluated. Fifteen patients in the Intensive Learning Center (ILC) program were assessed at 5- and 10-month intervals following baseline. In addition, their functioning was compared to a criterion related comparison group of 26 patients who had been transferred to community placements 18 months earlier. Two informant driven measures were used: The Rehabilitation Evaluation of Hall and Baker (REHAB), (Baker & Hall, 1988) and, Adaptive Behavior Scale (ABS), (Nihira, Foster, Shellhaas, & Leland, 1975). The results indicated significant improvement in the ILC patients adaptive functioning after 5 months, but this improvement was not consistently sustained at the 10 month follow-up. Comparisons between the ILC and community groups were made at 10 months and suggested considerable overlap in functioning between the two groups. The implications of the findings for program development and implementation as well as for discharge planning are discussed.     

An Implementation Study of Relationship Checkups as Home Visitations for Low‐Income At‐Risk Couples

Couples with the greatest need for relationship health maintenance and intervention are often least able to afford and access it; therefore, accessible, affordable, effective, and brief interventions are needed to improve relationship health for those who need it most. Consequently, this paper examined whether a brief relationship intervention could be effectively implemented with a low‐income, underserved population. All enrolled participants (N = 1,312) received the Relationship Checkup, which consists of an assessment and a feedback session delivered in their homes or at a local clinic at their request. Measures assessed relationship satisfaction, communication, psychological and physical aggression, and intimacy at baseline and 1‐month follow‐up, and program and relationship satisfaction at 6‐month follow‐up. All participants reported significant improvements on all outcomes with small effect sizes. However, moderation analyses suggested that distressed couples reported significantly larger effects across the board. Overall, participants reported that they were highly satisfied with the intervention both immediately after its delivery and 6 months later. Findings provide preliminary support for the effectiveness of this brief checkup and point to the utility of offering these kinds of low‐cost brief interventions in flexible formats for those who might have the most difficulty accessing them.     

Group evaluations as self-group distancing: Ingroup typicality moderates evaluative intergroup bias in stigmatized groups

Outgroup favoritism among members of stigmatized groups can be seen as a form of self-group distancing. We examined how intergroup evaluations in stigmatized groups vary as a function of ingroup typicality. In Studies 1 and 2, Black participants (N = 125,915; N = 766) more strongly preferred light-skinned or White relative to dark-skinned or Black individuals the lighter their own skin tone. In Study 3, overweight participants (N = 147,540) more strongly preferred normal-weight relative to overweight individuals the lower their own body weight. In Study 4, participants with disabilities (N = 35,058) more strongly preferred non-disabled relative to disabled individuals the less visible they judged their own disability. Relationships between ingroup typicality and intergroup evaluations were at least partially mediated by ingroup identification (Studies 2 and 3). A meta-analysis across studies yielded an average effect size of r = .12. Furthermore, higher ingroup typicality was related to both ingroup and outgroup evaluations. We discuss ingroup typicality as an individual constraint to self-group distancing among stigmatized group members and its relation to intergroup evaluations.
