Association among items from the self-report version of the Hamilton Depression Scale (Carroll Rating Scale) and respondents' sex

The association among items of the self-reported version of the Hamilton Depression Scale (Carroll Rating Scale), answered according to a memory of a maximally disturbing event experienced, and respondents' sex was examined in a nonclinical sample of 320 college students, 164 women (M age=21.7 yr., SD=3.6) and 156 men (M age=23.5 yr., SD=5.8). An assessment of sex bias was also evaluated. Multiple regression analysis showed that statements regarding unhappiness, urge to cry, dizziness and faintness, and waking in the middle of the night were significantly associated with women. Removal of these items from the Carroll Rating Scale Total scores eliminated the sex differences in depression rates. Items that displayed significant sex bias were those regarding behavior and emotions commonly attributed to women within the general population.     

Enhancing challenged students' recognition of mathematical relations through differential outcomes training

Previous studies have reported that the differential outcomes procedure enhances learning and memory in special populations with cognitive deficits (see Goeters, Blakely, & Poling, 1992, for a review). In the present study we extend these findings to healthy adults who were asked to discriminate between the symbols " > " and " < " in mathematical statements. In Experiment 1, the performance of participants who showed difficulties in discriminating between these symbols was better (shorter response times) for the differential outcomes condition than for the nondifferential outcomes condition. In Experiment 2, the difficulty of the task was increased by using signed decimal numbers. Similar to Experiment 1, participants who initially had difficulties in discriminating between the symbols showed better performance (higher accuracy) for the differential outcomes condition than for the nondifferential outcomes condition, but only when both numbers were negative. These findings suggest that the differential outcomes procedure can be used to improve performance of challenged healthy adults on discrimination tasks with mathematical symbols and relations.     

Extinction in multiple contexts does not necessarily make extinction less vulnerable to relapse

Three fear-conditioning experiments with rat subjects examined the effects of extinction in multiple contexts on a final relapse (renewal) effect that occurred when the extinguished fear cue was tested in a new context (Experiments 1 and 3) or in the context in which fear conditioning had first occurred (Experiment 2). Rats that received extinction in three contexts demonstrated more fear during extinction than rats that received the same number and temporal distribution of extinction trials in one context; extinction was partially lost with each context switch. Although extinction in multiple contexts thus had an impact on extinction behavior, it did not reduce the size of the final renewal effect. Fear during extinction was occasionally positively correlated with fear during final testing, but the two were never negatively correlated. The results suggest that extinction in multiple contexts does not necessarily weaken fear renewal, and that extinction procedures that generate high levels of responding in extinction do not necessarily make extinction learning less context-specific.     

Flexible conceptual projection of time onto spatial frames of reference

Flexibility in conceptual projection constitutes one of the most challenging issues in the embodiment and conceptual metaphor literatures. We sketch a theoretical proposal that places the burden of the explanation on attentional dynamics in interaction with mental models in working memory that are constrained to be maximally coherent. A test of this theory is provided in the context of the conceptual projection of time onto the domain of space. Participants categorized words presented at different spatial locations (back–front, left–right) as referring to the past or to the future. Responses were faster when the irrelevant word location was congruent with the back–past, front–future metaphoric mapping. Moreover, when a new highly task-relevant spatial frame of reference was introduced, it changed the projection of past and future onto space in a way that was congruent with the new frame (past was now projected to left space and future to right space), as predicted by the theory. This study shows that there is substantial flexibility in conceptual projection and opens a venue to study metaphoric variation across tasks, individuals, and cultures as the result of attentional dynamics.     

Differential age effects on attention-based inhibition: inhibitory tagging and inhibition of return

The purpose of this study was to determine whether 2 forms of attentional inhibition, inhibition of return (IOR) and inhibitory tagging, are differentially affected by the aging process. The authors tested 24 younger adults (mean age = 22 years) and 24 older adults (mean age = 69 years) on a combined IOR and Stroop task (Vivas & Fuentes, 2001). As predicted, younger adults' performance was consistent with inhibitory tagging of objects at inhibited locations. Although older adults demonstrated intact IOR, there was no evidence of inhibitory tagging. The results suggest that age deficits in inhibition are selective.     

Self-talk and affective problems in college students: valence of thinking and cognitive content specificity

The aim of this study was to develop a Self-Talk Inventory for young adults. This inventory consisted of two scales. The Negative Self-Talk Scale included three categories of self-talk (depressive, anxious, and angry thoughts) and the Positive Self-Talk Scale, three categories (minimization, positive orientation, and coping self-instructions). Participants were 982 undergraduate students (Mean age = 20.35 years, SD = 2.16). They completed the self-talk scales together with the following scales to measure symptoms of affective disorders: the Center for Epidemiological Studies Depression Scale (CES-D), the State-Trait Anxiety Inventory (STAI), and the State-Trait Anger Expression Inventory (STAXI-T). Factor analyses confirmed the hypothesized structure for the Self-Talk Inventory. The relations between self-talk and symptoms of affective disorders (depression, anxiety, and anger) were also evaluated. In general, states-of-mind -SOM- ratios and negative cognitions showed a greater association with psychological symptoms than did positive cognitions. Results concerning the cognitive characteristics of depression, anxiety, and anger were mixed and partially supported the cognitive content specificity theory.     

Default-mode network functional connectivity in aphasia: Therapy-induced neuroplasticity

Previous research on participants with aphasia has mainly been based on standard functional neuroimaging analysis. Recent studies have shown that functional connectivity analysis can detect compensatory activity, not revealed by standard analysis. Little is known, however, about the default-mode network in aphasia. In the current study, we studied changes in the default-mode network in subjects with aphasia who underwent semantic feature analysis therapy. We studied nine participants with chronic aphasia and compared them to 10 control participants. For the first time, we identified the default-mode network using spatial independent component analysis, in participants with aphasia. Intensive therapy improved integration in the posterior areas of the default-mode network concurrent with language improvement. Correlations between integration and improvement did not reach significance, but the trend suggests that pre-therapy integration of the default-mode network may predict therapy outcomes. Functional connectivity allows a better understanding of the impact of semantic feature analysis in aphasia.     

Individual Breaches of Environmental Laws in Cases from Public Administration Files

The characteristics of environmental transgressions and transgressors involved in 1,505 files handled by 4 public administrations were assessed. These administrations were in charge of environmental law enforcement in a highly protected setting, across federal, state, island, and municipality jurisdictions. Special attention was given to the transgressors' written responses to administrative sanctions included in the files. These were analyzed integrating the approaches of neutralization techniques and of accounts as strategies of conflict management. Results suggest that most environmental transgressions under study were carried out by private individuals in the personal domain of everyday life, and that transgressors' accounts of environmental transgressions were short, straightforward, and questioned the legitimacy of the environmental law being broken.     

Validity and Reliability of Three Rating Scales to Assess Practitioners’ Skills to Conduct Collaborative,Strength-Based,Systemic Work in Family-Based Services

This study analyzed the reliability and validity of three rating scales designed to assess practitioners’ skills in conducting systemic, collaborative, and strength-based assessments and interventions with multi-challenged families in family-based community services. The three scales, which assess reception and assessment skills, basic skills, and skills to support change, revealed good psychometric properties considering their construct validity, internal consistency, and inter-rater agreement. The results are discussed considering future research and possible applications of the scales in research and practice.     

The Effect of Warnings to Timeout on Child Compliance to Parental Instructions

ABSTRACT

One common component of behavioral parent training packages is the use of a warning prior to implementation of a timeout following noncompliance to parental instructions. The primary purpose of this research was to evaluate the effects of warnings on compliance. An alternating treatments design was used to evaluate compliance to warned versus unwarned timeouts with three typically developing children. All participants showed a significant increase in compliance upon implementation of the timeout package, either with or without a warning. However, compliance decreased over time in the Warning condition for two participants and increased in variability for a third. All participants had more timeouts in the No Warning condition. Results also showed preliminary evidence for parental preference of Warned timeouts. Implications are discussed.
