The growth of reading skills in children with Down Syndrome

There appears to be a close and probably causal relationship between early variations in phoneme skills and later reading skills in typically developing children, though the pattern in children with Down Syndrome is less clear. We present the results of a 2-year longitudinal study of 49 children with Down Syndrome (DS) and 61 typically developing (TD) control children with similar initial levels of reading skill. Phoneme awareness and vocabulary were strong concurrent predictors of initial levels of reading skill in both groups. However, longitudinally phoneme awareness was a predictor of the growth of reading skills in TD children but not in children with DS. There was a very high degree of longitudinal stability in reading skills in children with DS, and initial levels of reading skills seemed to be highly constrained by general language skills, as indexed by vocabulary knowledge, in this population. We conclude that reading development in children with DS shows similarities and differences to the pattern observed in TD children and that phoneme awareness appears to be a less powerful influence on the development of reading skills in children with DS.     

Heterogeneity of auditory verbal working memory in schizophrenia

The heterogeneity of schizophrenia remains an obstacle for understanding its pathophysiology. Studies using a tone discrimination screening test to classify patients have found evidence for 2 subgroups having either a specific deficit in verbal working memory (WM) or deficits in both verbal and nonverbal memory. This study aimed to (a) replicate in larger samples differences between these subgroups in auditory verbal WM; (b) evaluate their performance on tests of explicit memory and sustained attention; (c) determine the relation of verbal WM deficits to auditory hallucinations and other symptoms; and (d) examine medication effects. The verbal WM and tone discrimination performance did not differ between medicated (n = 45) and unmedicated (n = 38) patients. Patients with schizophrenia who passed the tone screening test (discriminators; n = 60) were compared with those who did not (nondiscriminators; n = 23) and healthy controls (n = 47). The discriminator subgroup showed poorer verbal WM than did controls and a deficit in verbal but not visual memory on the Wechsler Memory Scale-Revised (Wechsler, 1987), whereas the nondiscriminator subgroup showed overall poorer performance on both verbal and nonverbal tests and a marked deficit in sustained attention. Verbal WM deficits in discriminators were correlated with auditory hallucinations but not with negative symptoms. The results are consistent with a verbal memory deficit in a subgroup of schizophrenia having intact auditory perception, which may stem from dysfunction of language-related cortical regions, and a more generalized cognitive deficit in a subgroup having auditory perceptual and attentional dysfunction.     

Perceived risk of female infidelity moderates the relationship between objective risk of female infidelity and sexual coercion in humans (Homo sapiens)

Female extrapair copulation (EPC) can be costly to a woman's long-term romantic partner. If a woman has copulated recently with a man other than her long-term partner, her reproductive tract may contain the sperm of both men, initiating sperm competition (whereby sperm from multiple males compete to fertilize an egg). Should the woman become pregnant, her long-term partner is at risk of cuckoldry-investing unwittingly in offspring to whom he is not genetically related. Previous research in humans (Homo sapiens) and in nonhuman animals suggests that males have evolved tactics such as partner-directed sexual coercion that reduce the risk of cuckoldry. The current research provides preliminary evidence that mated men (n = 223) at greater risk of partner EPC, measured as having spent a greater proportion of time apart from their partner since the couple's last in-pair copulation, more frequently perform partner-directed sexually coercive behaviors. This relationship is moderated, however, by men's perceived risk of partner EPC, such that the correlation between the proportion of time spent apart since last in-pair copulation and sexually coercive behaviors remains significant only for those men who perceive themselves to be at some risk of partner EPC. Discussion addresses limitations of this research and highlights directions for future research investigating the relationship between female EPC and men's partner-directed sexual coercion.     

Social class rank, threat vigilance, and hostile reactivity

Lower-class individuals, because of their lower rank in society, are theorized to be more vigilant to social threats relative to their high-ranking upper-class counterparts. This class-related vigilance to threat, the authors predicted, would shape the emotional content of social interactions in systematic ways. In Study 1, participants engaged in a teasing interaction with a close friend. Lower-class participants--measured in terms of social class rank in society and within the friendship--more accurately tracked the hostile emotions of their friend. As a result, lower-class individuals experienced more hostile emotion contagion relative to upper-class participants. In Study 2, lower-class participants manipulated to experience lower subjective socioeconomic rank showed more hostile reactivity to ambiguous social scenarios relative to upper-class participants and to lower-class participants experiencing elevated socioeconomic rank. The results suggest that class affects expectations, perception, and experience of hostile emotion, particularly in situations in which lower-class individuals perceive their subordinate rank.     

It ain’t over ‘til it’s over: The effect of task completion on the savoring of success

The present research investigated a common yet to date unexamined assumption that individuals are unlikely to savor success when they have not yet fully completed a task. In Study 1 (N = 83), we assessed savoring responses of soccer players who were either winning or were tied at the end of the first half (in progress) and at the end of the match (completed). In Study 2 (N = 121 undergraduates), performance feedback (successful vs. average) and task completion (in progress vs. completed) were manipulated and savoring was assessed. In both studies, successful individuals reported savoring their positive experience less when the task was in progress as compared to completed. Results of a third study (N = 152 undergraduates) showed that lower savoring of success was due to individuals’ focus on and worries about future performance as well as the perception that positive emotions have limited utility. We discuss these findings in terms of the consequences for performance and well-being.     

The Disappearing Student

359 randomly selected freshmen (1962) at the University of New Mexico were sent a questionnaire related to college attrition, and the attitudes of withdrawees and continuers were compared regarding teachers, counselors, facilities, and various personal experiences and conditions that might lead to withdrawal. The results failed to support reasons for attrition commonly cited in the literature. Only 5 items distinguished the groups' reaction to the college environment. In fact, the continuers were more negative toward the college environment than the withdrawees. Only 3 reasons generally related to attrition differentiated the groups: withdrawees felt that problems of marriage, family finance, and general unhappiness were somewhat more important than did the continuers. These findings indicate that the real causes for college withdrawal have yet to be discovered.     

Are self-deceivers enhancing positive affect or denying negative affect? Toward an understanding of implicit affective processes

Self-deception is an important construct in social, personality, and clinical literatures. Although historical and clinical views of self-deception have regarded it as defensive in nature and operation, modern views of this individual difference variable instead highlight its apparent benefits to subjective mental health. The present four studies reinforce the latter view by showing that self-deception predicts positive priming effects, but not negative priming effects, in reaction time tasks sensitive to individual differences in affective priming. In all studies, individuals higher in self-deception displayed stronger positive priming effects, defined in terms of facilitation with two positive stimuli in a consecutive sequence, but self-deception did not predict negative priming effects in the same tasks. Importantly, these effects occurred both in tasks that called for the retrieval of self-knowledge (Study 1) and those that did not (Studies 2–4). This broad pattern supports substantive views of self-deception rather than views narrowly focused on self-presentation processes. Implications for understanding self-deception are discussed.     

Couple Conflict in Parents of Children with versus without Autism: Self-Reported and Observed Findings

We compared the couple conflict of parents of children with autism spectrum disorder (ASD) to a comparison group of parents of children without disabilities using self-reported and observational measures. In total, 178 couples who had a child with ASD (aged 5–12 years) and 174 couples who had children without disabilities (aged 5–12 years), recruited from a Midwestern state in the United States, reported on couple conflict in everyday life and engaged in an observed couple conflict interaction. Parents of children with ASD reported more frequent, severe, and unresolved couple problems than the comparison group. Parents who had a child with ASD were observed to have less engaged, balanced, and cooperative couple conflict interactions, but demonstrated more positive affect and sensitivity towards one another, than parents in the comparison group. Group differences had small effect sizes. Findings have implications for marital therapy and relationship education programs.
