Implicit learning of first-, second-, and third-order transition probabilities

Most sequence-learning studies have confounded different types of information, making it difficult to know precisely what is learned. Addressing many of the confounds, the current study shows that people can learn 1st-, 2nd-, and 3rd-order transition probabilities. Measures directly assessing awareness of the probabilities show that the knowledge is implicit early in training and becomes explicit with extended training.     

Depression and Self-Esteem in Boys with Attention-Deficit/Hyperactivity Disorder: Associations with Comorbid Aggression and Explanatory Attributional Mechanisms

It was tested whether boys with attention-deficit/hyperactivity disorder (ADHD), subgrouped by aggressive status, would show higher rates of depressive symptomatology and lower levels of self-esteem than would comparison boys and, in a subsample, explored attributional mechanisms that may be related to such internalizing features. Study 1 utilized 114 boys with ADHD (all prior recipients of stimulant medication) and 87 comparison boys, aged 7–12 years. Aggressive boys with ADHD reported more symptoms of depression than did nonaggressive boys with ADHD, who, in turn, reported more depression than did comparison boys. Effect sizes were moderate to large and did not vary with a depression rating scale uncontaminated by ADHD-related items. For self-esteem, the most pronounced effect was that aggressive boys with ADHD showed lower levels than did nonaggressive ADHD or comparison boys; effects were again moderate to large. Study 2 participants were a subsample of boys with ADHD from Study 1 (N = 27). We probed causal attributions in ADHD-related domains through responses to hypothetical vignettes, in which the protagonist's medication status (medicated, not medicated) was crossed with type of outcome (good, bad). Medication-related attributions were frequent. In describing the protagonist's success in relation to medication treatment, the sample showed significant associations between (a) medication-related attributions and (b) increased depressive symptomatology as well as decreased self-esteem. We discuss attributional processes that may help to explain the variation in internalizing symptoms among children with ADHD.     

How do I appear to others? Social anxiety and processing of the observable self

Two information processing biases that could maintain social anxiety were investigated. High and low socially anxious individuals encoded positive and negative trait words in one of three ways: public self-referent, private self-referent, and other-referent. Half were then told they would soon have to give a speech. As predicted, compared to low socially anxious individuals, high socially anxious individuals recalled less positive public self-referent words, but only when both groups were anticipating giving a speech. No memory biases were observed for private self-referent or other-referent words. Next all participants gave a speech. Correlational analyses suggested that high socially anxious individuals may use the somatic concomitants of anxiety to overestimate how anxious they appear and underestimate how well they come across.     

An experimental investigation of the role of safety-seeking behaviours in the maintenance of panic disorder with agoraphobia.

This study evaluates the hypothesis that safety-seeking behaviours play an important role in maintaining anxiety because they prevent patients from benefiting from disconfirmatory experience. Patients suffering from panic disorder with agoraphobia carried out a behaviour test, closely followed by an experimental session, which included a brief (15 min) period of exposure during which participants either stopped or maintained within-situation safety-seeking behaviours. When the behaviour test was repeated within two days, patients who had stopped their safety-seeking behaviours during the experimental session showed a significantly greater decrease in catastrophic beliefs and anxiety than those who had maintained safety-seeking behaviour. This difference was also reflected in questionnaires measuring clinical anxiety. These results are consistent with the cognitive hypothesis.     

A New Model for Premarital Counseling Within the Church

The divorce rate among Christians is higher than that of the average population. This statistic is cause for concern and change in church preparation for marriage. Although instruction for pastoral premarital counseling exists, most churches do not follow the minimum guidelines. Churches need a new proactive model for building good marriages rather than mending broken ones. This article presents one such model for marriage preparedness.

Further Support for a Hierarchical Model of Affect: Reply to Green and Salovey

Green and Salovey agree with us that happiness and sadness are strongly bipolar, and that Positive and Negative Activation are not. However, Green and Salovey subscribe to the two-dimensional circumplex, a model we find wanting. Actually, the problems they discuss arise from the limitations of the circumplex rather than from issues fundamental to affective structure. And they do not consider the evidence, reported in our target article, that supports an alternative to the circumplex: a three-level hierarchical model. In this reply, we take a closer look at the empirical findings supporting this model, and we emphasize its heuristic promise.     

Dissociation between the effects of damage to perirhinal cortex and area TE

Perirhinal cortex and area TE are immediately adjacent to each other in the temporal lobe and reciprocally interconnected. These areas are thought to lie at the interface between visual perception and visual memory, but it has been unclear what their separate contributions might be. In three experiments, monkeys with bilateral lesions of the perirhinal cortex exhibited a different pattern of impairment than monkeys with bilateral lesions of area TE. In experiment 1, lesions of the perirhinal cortex produced a multimodal deficit in recognition memory (delayed nonmatching to sample), whereas lesions of area TE impaired performance only in the visual modality. In experiment 2, on a test of visual recognition memory (the visual paired comparison task) lesions of the perirhinal cortex impaired performance at long delays but spared performance at a very short delay. In contrast, lesions of area TE impaired performance even at the short delay. In experiment 3, lesions of the perirhinal cortex and lesions of area TE produced an opposite pattern of impairment on two visual discrimination tasks, simple object discrimination learning (impaired only by perirhinal lesions), and concurrent discrimination learning (impaired only by TE lesions). Taken together, the findings suggest that the perirhinal cortex, like other medial temporal lobe structures, is important for the formation of memory, whereas area TE is important for visual perceptual processing.     

Benchmark Memories in Adulthood: Central Domains and Predictors of Their Frequency

This study extended earlier research on the reminiscence bump phenomenon in autobiographical memory by examining the central domains and predictors of benchmark memories from a life history timeline and from three selected significant events. Memories elicited by these methods demonstrated the reminiscence bump as occurring in early adulthood. The central domains representing this era involved events with family and relationships followed by those related to education and work. Individual differences in socio-emotional variables associated with self and identity formations (i.e., family climate, defensive style, self-complexity, and adult attachment) were associated with the reminiscence bump. These findings support the self-narrative hypothesis that the reminiscence phenomenon is related to the process of identity formation in late adolescence and early adulthood.     

Counseling Older Adults with Dementia: A Survey of Therapists in Massachusetts

Although much has been written about therapeutic interventions with caregivers, little is known about the counseling services that are available for victims of dementia. The present study was designed to explore community mental health center (CMHC) services and therapists' experiences in providing psychotherapy to this population in Massachusetts. Only 27 of the 36 CMHCs in the state reported providing mental health services to older adults with a dementing illness. A survey of therapists who specialized in working with older adults found that the percentage of older adult clients estimated to have dementia averaged about half of their caseload. Older persons in the early phase of a dementing illness were most frequently referred for depression and anxiety, whereas those with moderate decline were most frequently referred for management of disruptive behavior. The most common services provided to clients with dementia consisted of assessment and individual counseling. The latter finding indicates a discrepancy between what is practiced and the professional literature. Most of the psychotherapy described in the literature concerns group interventions, which were rarely provided by the mental health centers in Massachusetts. The centers tended to offer individual counseling; however, little information on how to provide this form of treatment can be found.
