The role of optimism in the interpersonal-psychological theory of suicidal behavior

A possible relationship between Joiner's (2005) interpersonal-psychological theory of suicidal behavior and optimism was investigated by examining the ability of optimism to act as a moderator of perceived burdensomeness, thwarted belongingness, and acquired capability to engage in self-injury in the prediction of suicidal ideation. Results supported hypotheses that optimism would serve as a moderator of the effects of thwarted belongingness and perceived burdensomeness in the prediction of suicidal ideation; however, similar results were not found regarding the acquired capability to engage in self-injury. How optimism might play a role in alleviating suicidal ideation and clinical implications of the findings are discussed.     

Personality traits and autobiographical memory: Openness is positively related to the experience and usage of recollections

We examined the relationship between the Five-Factor Model of personality and the experience and overall usage of autobiographical memory in two studies. In both studies we found that Openness was related to the directive and self functions of overall usage. In addition, Openness was related to the vividness, reliving, coherence, and centrality of event to the person's identity and life story of concrete memories in Study 2, whereas this was not found in Study 1. For the remaining "Big Five" personality traits the results were less consistent across studies. Neuroticism was related to the self function in Study 1, but also to the directive function as well as to negative affect of concrete memories in Study 1. Extraversion was positively related to the social function as well as to conversational rehearsal of memories in Study 1, but this was also not replicated in Study 2. Finally, in both studies there were no significant relationships with regard to Agreeableness and Conscientiousness. Overall, the findings replicate and extend previous work showing a positive relationship between Openness and the experience and overall usage of autobiographical memory, whereas the roles for the remaining "Big Five" are less clear.     

Guidance of attention to objects and locations by long-term memory of natural scenes

Four flicker change-detection experiments demonstrate that scene-specific long-term memory guides attention to both behaviorally relevant locations and objects within a familiar scene. Participants performed an initial block of change-detection trials, detecting the addition of an object to a natural scene. After a 30-min delay, participants performed an unanticipated 2nd block of trials. When the same scene occurred in the 2nd block, the change within the scene was (a) identical to the original change, (b) a new object appearing in the original change location, (c) the same object appearing in a new location, or (d) a new object appearing in a new location. Results suggest that attention is rapidly allocated to previously relevant locations and then to previously relevant objects. This pattern of locations dominating objects remained when object identity information was made more salient. Eye tracking verified that scene memory results in more direct scan paths to previously relevant locations and objects. This contextual guidance suggests that a high-capacity long-term memory for scenes is used to insure that limited attentional capacity is allocated efficiently rather than being squandered.     

Sex-specific clinical correlates of hoarding in obsessive-compulsive disorder

Little is known about whether the clinical correlates of hoarding behavior are different in men and women with obsessive-compulsive disorder (OCD). In the current study, we evaluated the association of hoarding with categories of obsessions and compulsions, psychiatric disorders, personality dimensions, and other clinical characteristics separately in 151 men and 358 women with OCD who were examined during the OCD Collaborative Genetics Study. We found that, among men but not women, hoarding was associated with aggressive, sexual, and religious obsessions and checking compulsions. In men, hoarding was associated with generalized anxiety disorder and tics whereas, among women, hoarding was associated with social phobia, post-traumatic stress disorder, body dysmorphic disorder, nail biting, and skin picking. In women but not men, hoarding was associated with schizotypal and dependent personality disorder dimensions, and with low conscientiousness. These findings indicate that specific clinical correlates of hoarding in OCD are different in men and women and may reflect sex-specific differences in the course, expression, and/or etiology of hoarding behavior in OCD.     

THE ACQUISITION OF SIMPLE AND COMPOUND SENTENCE STRUCTURE IN AN AUTISTIC CHILD1

Contingent reinforcement and imitative prompts were used to teach an autistic child to use simple and compound sentences to describe a set of standard pictures. When imitative prompts and reinforcement were discontinued, correct use of simple sentences declined, but increased again when imitative prompts and reinforcement were re-instated. When imitative prompts and reinforcements were used to teach compound sentence structure, correct use of simple sentences declined and correct use of compound structure increased. At the end of training, the child also used novel compound sentences to describe a set of pictures on which he had received no direct training.     

Attention and memory cues in concept learning as a function of task complexity and age

The effects of attention and memory cues on concept learning performance were investigated as a function of task complexity and grade level of Ss. It was found that: (1) the attention and memory cues were closely interrelated in their effects upon performance with both significantly improving performance at all but the lowest levels of complexity; (2) both types of cues considerably lessened the effect of stimulus complexity upon performance; and (3) the attention cue elicited the best performance from Ss in the first through ninth grades, while the memory cue elicited the best performance from 4-year-old and kindergarten Ss.     

Clarifying the convergence between obsessive compulsive personality disorder criteria and obsessive compulsive disorder

In this study we examined the convergence between obsessive-compulsive personality disorder (OCPD) criteria and obsessive-compulsive disorder (OCD). Baseline assessments of 629 participants of the Collaborative Longitudinal Personality Disorders Study were used to examine the associations between OCPD criteria and diagnoses of OCD. Three of the eight OCPD criteria--hoarding, perfectionism, and preoccupation with details--were significantly more frequent in subjects with OCD (n = 89) than in subjects without OCD (n = 540). Logistic regressions were used to predict the probability of each OCPD criterion as a function of Axis I diagnoses (OCD, additional anxiety disorders, and major depressive disorder). Associations between OCD and these three OCPD criteria remained significant in the logistic regressions, showing unique associations with OCD and odds ratios ranging from 2.71 to 2.99. In addition, other anxiety disorders and major depressive disorder showed few associations with specific OCPD criteria. This study suggests variability in the strength of the relationships between specific OCPD criteria and OCD. The findings also support a unique relationship between OCPD symptoms and OCD, compared to other anxiety disorders or major depression. Future efforts to explore the link between Axis I and Axis II disorders may be enriched by conducting analyses at the symptom level.     

The effects of fixed-time reinforcement schedules on problem behavior of children with emotional and behavioral disorders in a day-treatment classroom setting

The current study assessed the effects of fixed-time reinforcement schedules on problem behavior of students with emotional-behavioral disorders in a clinical day-treatment classroom setting. Three elementary-aged students with a variety of emotional and behavioral problems participated in the study. Initial functional assessments indicated that social attention was the maintaining reinforcer for their verbally disruptive behavior. Baseline phases were alternated with phases in which attention was provided on fixed-time schedules in the context of an ABAB design. The results indicated that the provision of attention on fixed-time schedules substantially reduced the participants' rate of verbal disruptions. These decreases were maintained during initial thinning of the schedules. The results provide one of the first examples that such an intervention can be successfully implemented in a classroom setting.
