Infants of depressed mothers,although competent learners,fail to learn in response to their own mothers' infant-directed speech

Depressed mothers use less of the exaggerated prosody that is typical of infant-directed (ID) speech than do nondepressed mothers. We investigated the consequences of this reduced perceptual salience in ID speech for infant learning. Infants of nondepressed mothers readily learned that their mothers' speech signaled a face, whereas infants of depressed mothers failed to learn that their mothers' speech signaled the face. Infants of depressed mothers did, however, show strong learning in response to speech produced by an unfamiliar nondepressed mother. These outcomes indicate that the reduced perceptual salience of depressed mothers' ID speech could lead to deficient learning in otherwise competent learners.     

Making human research safe: Why we cannot afford to fail

This paper was given as a keynote address at the international conference on Ethics of Intellectual Property Rights and Patents held in Warsaw, Poland on April 23–24, 2004. The address was the introductory presentation to the important topic of protecting individuals who participate in research as research subjects.     

Electrophysiological responses in mothers to their own and unfamiliar child's gaze information

An attachment bond between a mother and her child is one of the most intimate human relationships. It is important for a mother to be sensitive to her child's gaze direction because exchanging gaze information plays a vital role in their relationship. Furthermore, recent studies have revealed differential neural activation patterns in mothers when presented the faces of their own children or the unfamiliar child of other people. Based on these findings, in the present study, we investigated whether mothers show differential neural responses to gaze information of their own child compared to that of an unfamiliar child. To this end, event-related-potentials elicited by the faces of one's own or an unfamiliar child with straight or averted gaze directions were measured using an oddball-paradigm. The results showed that peak amplitudes of the N170 component were enlarged by viewing the straight gazes compared to the averted gazes of one's own child, but not of an unfamiliar child. When the gaze was directed straight, the P3 amplitude elicited by one's own child's face is smaller than that elicited by an unfamiliar child's face. P3s elicited in viewing one's own child's face with averted gaze and in viewing an unfamiliar child's face with straight gaze were positively correlated with state-anxiety. These results bolster the hypothesis that processing the gaze information of one's own child elicits differential neural activation compared to the gaze information of an other person's unfamiliar child at both perceptual and evaluative stages of face processing.     

Intolerance of uncertainty,causal uncertainty,causal importance,self-concept clarity and their relations to generalized anxiety disorder

Although numerous studies have provided support for the notion that intolerance of uncertainty plays a key role in pathological worry (the hallmark feature of generalized anxiety disorder (GAD)), other uncertainty-related constructs may also have relevance for the understanding of individuals who engage in pathological worry. Three constructs from the social cognition literature, causal uncertainty, causal importance, and self-concept clarity, were examined in the present study to assess the degree to which these explain unique variance in GAD, over and above intolerance of uncertainty. N = 235 participants completed self-report measures of trait worry, GAD symptoms, and uncertainty-relevant constructs. A subgroup was subsequently classified as low in GAD symptoms (n = 69) or high in GAD symptoms (n = 54) based on validated cut scores on measures of trait worry and GAD symptoms. In logistic regressions, only elevated intolerance of uncertainty and lower self-concept clarity emerged as unique correlates of high (vs. low) GAD symptoms. The possible role of self-concept uncertainty in GAD and the utility of integrating social cognition theories and constructs into clinical research on intolerance of uncertainty are discussed.     

Integrating immigrant minorities: developing a scale to measure majority members' attitudes toward their own proactive efforts

The present study is based on the premise that the integration of ethnic minorities may involve more than the majority's expression of tolerance. In order to promote inclusion, the majority may have to play a more active role in the integration process. We describe the development and validation of a new psychometric scale which assesses majority members' attitudes toward their own proactive contribution to the integration of immigrants within three domains: cultural and structural efforts, and openness to diversity. The scale is investigated by analyses of internal structure and exploration of construct validity in relation to relevant social psychological and personality constructs in a sample of 486 Norwegian university students (28% male, mean age = 26.5, SD = 6.08). Factor analyses supported a unidimensional structure and the estimated reliability of an additive scale was satisfactory (Cronbach's α = 0.91). The scale correlated negatively with measures of right-wing authoritarianism and social dominance orientation, and positively with global identity. It was weakly related to the personality traits agreeableness, intellect, extraversion, and conscientiousness. The potential utility of the scale in both applied and experimental social psychological studies are discussed.     

Assessing individual differences in the degree to which people are committed to following their beliefs

The authors developed a new dispositional measure of Commitment to Beliefs (CTB)—the degree to which people feel it is important to follow their value-expressive beliefs—across three phases of research. In Phases 1 and 2 (Studies 1-4), the CTB scale demonstrated strong internal consistency, and convergent and discriminant validity. Phase 3 demonstrated the scale’s predictive validity: high-CTB individuals were more likely to report engaging in activities during the past month and year that followed directly from their beliefs (Study 5), act on their beliefs when given the opportunity (Study 6), and show more polarized attitudes toward ideologically-relevant groups (Study 7). These findings illustrate the utility of a dispositional approach for examining the extent to which people follow their beliefs.

Deficits in the ability to recognize one's own affects and those of others: associations with neurocognition, symptoms and sexual trauma among persons with schizophrenia spectrum disorders

While many with schizophrenia experience deficits in metacognition it is unclear whether those deficits are related to other features of illness. To explore this issue, the current study classified participants with schizophrenia as possessing a deficit in both awareness of their own emotions and those of others (n = 30), aware of their own emotions but unaware of the emotions of others (n = 50) and aware of their own emotions and of other’s emotions (n = 17). Groups were compared on assessments of neurocognitive function, symptoms, and history of sexual trauma. ANCOVA controlling for education found that the group unaware of their own emotions and those of others demonstrated poorer verbal memory, processing speed, executive function, less emotional discomfort and higher levels of disorganization symptoms relative to the other groups. The group aware of their own emotions but not those of others had a significantly higher report of childhood sexual abuse.     

Mothers' responses to the cries of normal and premature infants as a function of the birth status of their own child

Mothers of premature and full-term infants viewed and heard videotapes of premature and full-term infants. The onset of crying by both infants elicited physiological arousal (evident in blood pressure, skin conductance, and heart rate increases) in the adults. The mothers of premature infants responded with especially marked arousal to the infants' cries. These mothers also reported that they were more attentive and alert while the infant was crying. The subjects responded similarly to the cries of full-term and premature infants. Mothers who described their own baby as easy exhibited a lower increase in diastolic blood pressure and heart rate, and reported being more alert, attentive, and willing to interact with the stimulus babies than those whose own baby appeared “difficult.”     

Reactions to Different Types of Forced Distribution Performance Evaluation Systems

Purpose  We isolate and describe four key elements that distinguish different forms of forced distribution systems (FDS). These key elements are the consequences for low performers, differentiation of rewards for top performers, frequency of feedback, and comparison group size. We examine how these elements influence respondents’ attraction to FDS. Design/methodology/approach  Undergraduate students (n = 163) completed a policy capturing study designed to determine how these four FDS elements influence their attraction to FDS. We examine the relative importance of these elements that most influence attraction to different FDS, as well as individual attributes (i.e., cognitive ability, gender, and major) that may affect those preferences. Findings  Respondents were most attracted to systems with less stringent treatment of low performers, high differentiation of rewards, frequent feedback and large comparison groups. Consequences for low performers were nearly twice as influential as any other element. Respondents with higher cognitive ability favored high reward differentiation and males were less affected by stringent consequences for low performers. Implications  Before practitioners implement FDS, it would be prudent to consider all four elements examined in this study—with the treatment of low performers being the most salient issue. Future accounts of FDS should clarify the nature of these elements when reporting on FDS. Such precision will be useful in generating a knowledge base on FDS. Originality/value   We add precision to the discussion of FDS by identifying four key elements. This is one of the first studies to examine perceptions of FDS from a ratee perspective.

Testing the ability of children with attention deficit hyperactivity disorder to accurately report the effects of medication on their behavior

Children with attention deficit hyperactivity disorder (ADHD) are often treated with central nervous system stimulants, making the evaluation of medication effects an important topic for applied behavior analysts. Because assessment protocols emphasize informant reports and direct observations of child behavior, little is known about the extent to which children themselves can accurately report medication effects. Double-blind placebo-controlled procedures were used to examine whether 6 children with ADHD could recognize the effects of their medication. The children were given math worksheets to complete for 15 min during each of 14 sessions while on medication and placebo. Children completed a self-evaluation form at the end of each session, and ratings were compared to observed behavior and academic performance. Results indicated that 3 children were able to accurately report their medication status at levels greater than chance, whereas the accuracy of reports by all children was related to dosage level, differences in behavior, and the presence of adverse effects. The implications of these results for placebo-controlled research, self-monitoring of dosage levels, and accuracy training are discussed.
