The effect of age on rule-based category learning

An explicit, rule-based, category-learning task with abstract visual stimuli was administered to 50 healthy older adults and 48 younger adults. Accuracy and reaction time (RT) were examined for the effects of age, perceptual abilities, rule memory, rule complexity, stimulus novelty, and response competition. Older adults performed at equivalent levels to younger adults when applying a simple rule, but showed performance decrements when applying a more complex rule. The age effect interacted with both stimulus novelty and response competition, and was not eliminated after controlling for basic perceptual abilities and rule memory. The authors suggest that older adults show category learning deficits in conditions that require enhanced cognitive control. These results are discussed in reference to the growing body of literature regarding age-related change in executive abilities and frontal lobe function.     

Extracting core components of cognitive control

The facility with which humans perform and shift among a wide variety of cognitive tasks seems to indicate a mechanism for entering into a task-dependent mode or set. However, little is known about the neural systems that subserve task control. A recent neuroimaging study by Dosenbach et al. offers a set of novel methodological tools to examine this issue and uncovers new candidate brain regions for a core system that might implement task sets.     

Affective reactivity in language: the role of psychophysiological arousal

Several studies have found that individuals with schizophrenia and their relatives, as well as healthy controls, exhibit greater language disturbance when discussing affectively negative as compared to positive or neutral topics. The goal of this study was to test the hypothesis that negative emotion impairs language production, at least in part by increasing physiological arousal. The authors had 35 healthy adults produce speech in response to affectively negative, positive, and neutral questions while the authors recorded heart rate and skin conductance. Participants displayed greater amounts of reference errors, higher heart rates, and a higher frequency of nonspecific skin conductance responses when discussing affectively negative as compared to positive or neutral topics.     

Contrasting effects of self-schema priming on lexical decisions and interpersonal stroop task performance: evidence for a cognitive/interactionist model of interpersonal dependency

Four experiments tested a key tenet of Bornstein's (1992, 1993) cognitive/interactionist (C/I) model of interpersonal dependency: that priming the helpless self-schema (HSS) alters processing of dependency-related information in dependent--but not nondependent--individuals. Experiments 1 and 2 assessed the effects of subliminal lexical priming and an emotional priming manipulation on lexical decision (LD) judgments for dependency-related words and control words. Experiments 3 and 4 assessed the effects of these same priming procedures on Interpersonal Stroop Task (IST) performance. As predicted, priming the HSS produced contrasting effects on different outcome measures, decreasing LD latencies, but increasing IST response times. Results are discussed in the context of the C/I model, and suggestions for future studies are offered.     

Invisible overtures: fears of rejection and the signal amplification bias

Four studies demonstrated that fears of rejection prompt individuals to exhibit a signal amplification bias, whereby they perceive that their overtures communicate more romantic interest to potential partners than is actually the case. The link between rejection anxieties and the bias was evident regardless of whether fears of rejection were assessed in terms of chronic attachment anxiety or were induced by reflection on a previous rejection experience. Mediation analyses suggested that the bias stems in part from an expected-augmenting process, whereby persons with strong fears of rejection incorrectly assume that the recipient of their overtures will take their inhibitions into account when interpreting their behavior. Implications for understanding the link between attachment anxiety and loneliness and for designing social skills interventions are discussed.     

The shame of being undone by illness and the power of support through the body of Christ

This paper examines shame that arises from living with a body that has been undone by cancer or other serious illness. It draws on first-person narratives and social-scientific studies of cancer patients to explore how bodies undone by illness often cease to conform to cultural standards of health as well as gendered expectations of bodies, and how experiences of shame arise from those shifts in how sick bodies appear and perform. Analysis of narratives by and qualitative data about those who are seriously ill also reveals how the undoing of the body by illness often precipitates an undoing of one's sense of self that leads to experiences of shame over an inability to fill roles and expectations in ways that were possible in life before serious illness. The paper then utilizes biblical and theological resources to explore ways religious communities can make space for those living with serious illness to lament what it's like to be undone by illness, to hold them up amid their experiences of vulnerability through public lament and acts of accompaniment, and to affirm their worth in the eyes of God and in the body of Christ.     

Teaching the History of Counseling: Training the Next Generation

The authors describe a teaching activity using a poster-session format to teach first-year counseling psychology doctoral students the history of counseling. Evaluative data suggest that the format was an effective and powerful tool to teach beginning counseling psychology students the history of the profession. The implications of the evaluative feedback are discussed in terms of teaching and preparing the next generation of counselors.     

Confidentiality and the rape victim: ethical intent versus political reality

...The clinician who works with the victim of rape, either in hospital emergency departments, community mental health settings, college environments, or private practice, should consider ways that would effect the many overdue reforms for which this specialty cries out. The need for sensitivity in the area of record keeping, particularly as to how such records might be used, can hardly be debated. Beyond this, there is the role of patient advocate, calling upon the clinician to serve an educative function with reference to the members of his profession and of the larger society. Confidentiality of patient records can be preserved only to the extent that the cultural context in which they exist values such privacy.     

Gender Differences in Emotional Closeness Between Preschool Children and Their Mothers

The emotional closeness between mothers andtheir children was examined to determine if motherdaughter pairs exhibit closer emotional relationshipsthan mother son pairs. Forty-one mother childpredominantly Caucasian dyads were videotaped during asemistructured play setting. The children were 4 (10males and 10 females) and 5 years of age (10 males and11 females). Emotional closeness was defined as physical proximity, mutual eye contact, and global levelof enjoyment. Results demonstrated that compared toboys, girls were physically closer to their mothers,engaged in more mutual eye contact with their mothers, and were rated higher on global enjoyment.Results are consistent with Chodorow's theory thatgender identity development is related to the emotionalrelationships that develop between children and their mothers.     

The word-frequency paradox in recognition

High-frequency words are recalled better than are low-frequency words, but low-frequency words produce higher hit rates in a recognition test than do high-frequency words. Two experiments provided new date on the phenomenon and also evidence relevant to the dual process model of recognition, which postulates that recognition judgments are a function of increments in item familiarity and of item retrievability. First, recall and recognition by subjects who initially performed a single lexical decision task were compared with those of subjects who also gave definitions of high-, low-, and very low-frequency target words. In the second experiment, subjects initially performed either a semantic, elaborative task or an integrative task that focused attention on the physical, perceptual features of the same words. Both experiments showed that extensive elaborative processing results in higher recall and hit rates but lower false alarm rates, whereas word frequency has a monotonic, linear effect on recall and false alarm rates, but a paradoxical, curvilinear effect on hit rates. Elaboration is apparently more effective when the potential availability of meaningful connections with other structures is greater (as for high-frequency words). The results are consistent with the dual process model.
