Duration discrimination in the context of age,sex, and cognition

It has been proposed that the perception of very short duration is governed by sensory mechanisms, whereas the perception of longer duration depends on cognitive capacities. Four duration discrimination tasks (modalities: visual, auditory; base duration: 100 ms, 1000 ms) were used to study the relation between time perception, age, sex, and cognitive abilities (alertness, visual and verbal working memory, general fluid reasoning) in 100 subjects aged between 21 and 84 years. Temporal acuity was higher (Weber fractions are lower) for longer stimuli and for the auditory modality. Age was related to the visual 100 ms condition only, with lower temporal acuity in elder participants. Alertness was significantly related to auditory and visual Weber fractions for shorter stimuli only. Additionally, visual working memory was a significant predictor for shorter visual stimuli. These results indicate that alertness, but also working memory, are associated with temporal discrimination of very brief duration.     

Context effects and selective response lengthening in a temporal serial reproduction task

Repeatedly performing a temporal reproduction task has been reported to increase reproduced durations. We report the novel finding that the second reproduction in a series is selectively enhanced relative to the first. This was true regardless of whether the responses were discrete (separate start and stop responses) or contiguous (stop response is the start of the next response). In a final experiment we test the hypothesis that the second reproduction is more influenced by the central tendency of previously experienced durations than is the first. These results are discussed in terms of two sources of performance uncertainty: temporal remoteness of the second and subsequent reproductions from the standard and trial-by-trial unpredictability of the standard in random but not blocked designs.     

Simple rules for detecting depression

Depressive disorders are major public health issues worldwide. We tested the capacity of a simple lexicographic and noncompensatory fast and frugal tree (FFT) and a simple compensatory unit-weight model to detect depressed mood relative to a complex compensatory logistic regression and a naïve maximization model. The FFT and the two compensatory models were fitted to the Beck Depression Inventory (BDI) score of a representative sample of 1382 young women and cross validated on the women's BDI score approximately 18 months later. Although the FFT on average inspected only approximately one cue, it outperformed the naïve maximization model and performed comparably to the compensatory models. The heavier false alarms were weighted relative to misses, the better the FFT and the unit-weight model performed. We conclude that simple decision tools—which have received relatively little attention in mental health settings so far—might offer a competitive alternative to complex weighted assessment models in this domain.     

大学新生时间管理倾向、手机依赖与无聊倾向的关系：一项交叉滞后研究

在3个月的时间内对425名大学新生进行3次追踪测量，以考察时间管理倾向、手机依赖与无聊倾向之间的因果顺序和发展变化趋势。结果发现：（1）大学新生的无聊倾向与时间管理倾向呈同时性和继时性的负相关，并与手机依赖水平呈同时性和继时性的正相关。（2）T1和T2的无聊倾向分别正向预测T2和T3的手机依赖，并分别负向预测T2和T3的时间管理倾向；T1的时间管理倾向负向预测T2的无聊倾向；T2的手机依赖正向预测T3的无聊倾向。结论：无聊倾向分别与手机依赖、时间管理倾向之间存在相互预测关系。     

Measuring Change in OCD: Sensitivity of the Obsessive-Compulsive Inventory-Revised

This study examined the sensitivity to change and specificity of response of the Obsessive-Compulsive Inventory-Revised (OCI-R), an 18-item self-report measure of obsessive-compulsive disorder (OCD) severity. Seventy-seven OCD patients received cognitive-behavioral therapy incorporating exposure and response prevention (ERP). Change from pre- to posttest on the OCI-R was compared to changes as assessed by the Yale-Brown Obsessive Compulsive Scale (Y-BOCS) and other measures of OCD and related symptoms. Results suggest the OCI-R is sensitive to treatment effects and that pre- to posttest change on this instrument reflects improvement in OCD and related symptoms of depression, anxiety, and global functioning. The OCI-R was not sensitive to improvement in patients’ insight into the senselessness of their OCD symptoms. The OCI-R appears suitable for use in clinical settings and naturalistic outcome studies where time and resources do not permit administration of lengthy symptom interviews.     

The Client Cultural Competence Inventory: An Instrument for Assessing Cultural Competence in Behavioral Managed Care Organizations

The rapid growth in Behavioral Managed Care Organizations has led to increasing concern about the future availability of culturally competent mental health services for ethnic minorities. Prior efforts to assess cultural competence of mental health services have focused exclusively on agency providers and individual mental health professionals rather than on clients' perceptions of care. We introduce the Client Cultural Competence Inventory, which has several advantages over other cultural competence measures including its (a) lower susceptibility to social desirability bias, (b) ability to assess attitudes concerning a broader range of therapists, providers and plans, and (c) focus on clients rather than the psychiatric community as the central force in determining cultural competence. Preliminary psychometric analyses of the inventory are presented from data gathered in a group of parents with children who are severely emotionally disturbed.     

Fewer reasons for staying alive when you are thinking of killing yourself: The brief reasons for living inventory

The Linehan Reasons for Living Inventory is a 48-item scale on which respondents rate how important each item would be for living if suicide were contemplated. The inventory possesses good psychometric properties and can distinguish suicidal from nonsuicidal people among shoppers, psychiatric inpatients, college students, and adolescents. As its length limits its utility in many institutional and screening settings, the purpose of this study was (1) to develop a brief form of the Reasons for Living Inventory appropriate for clinical use and (2) to examine the predictive validity of this brief measure, named the Brief Reasons for Living Inventory (BRFL), to distinguish suicidal from nonsuicidal prison inmates. Results indicate that the brief form was as good as either the Beck Depression Inventory or the Beck Hopelessness Scale at predicting suicidality in this population. Further study is needed to validate the BRFL with different institutionalized and other populations as well as to assess its ability to discriminate suicide ideators from those engaging in overt suicidal behavior.Support for this project was provided in part by the New York State Office of Mental Health Bureau of Forensic Services and the New York State Department of Correctional Services.     

A resolution to the interpretive dilemmas created by the Minnesota Multiphasic Personality Inventory 2 (MMPI-2)? A reply to Ben-Porath and Graham

In my original article (Strassberg, 1991) I described (1)some of the changes introduced by the MMPI-2, (2) possible interpretive dilemmas created by these changes, and (3) strategies for dealing with these dilemmas. In their reply to my paper, Ben-Porath and Graham (preceding paper) suggest that the differences between the MMPI-2 and the MMPI (1) are to be expected, (2) are less important than I imply, and (3) when they do occur, will almost always reveal the superiority of the MMPI-2. In this reply to Ben-Porath and Graham, I explain why, despite their reassurances, I continue to contend that interpretive dilemmas can exist when using the MMPI-2, but these should not deter us from using this instrument.     

Interpretive dilemmas created by the minnesota multiphasic personality inventory 2 (MMPI-2)

While the new MMPI-2 has the potential to provide more and better clinically relevant information than its predecessor, its introduction also creates several important problems for clinicians and researchers. In particular, the new norms and the use of uniform (rather than linear) T-scores result in the same raw scores on the two tests yielding clinical profiles that can be quite different, both qualitatively and quantitatively. These differences can result in difficulty in MMPI-2 profile interpretation when the user is relying on MMPI interpretive strategies. This paper addresses these concerns and offers some temporary remedial strategies.     

Temporal perception in closed-skill sports: An experimental study on expert swimmers and runners

The cognitive benefits of closed-skill sports practice have so far been scantily investigated. Here, we thus focused on the potential impact of swimming and running - two sports that highly rely on a precise control of timing - on time processing. To investigate the impact of these closed-skill sports on time perception and estimation, three groups of participants (for a total of eighty-four young adults) took part in the present study: expert swimmers, expert runners, and non-athletes. The ability to process temporal information in the milliseconds and seconds range was assessed through a time reproduction and a finger-tapping tasks, while a motor imagery paradigm was adopted to assess temporal estimation of sport performance in a wider interval range. We also employed the Vividness of Movement Imagery Questionnaire to assess the individual's ability of motor imagery. Results showed that closed-skill sports, specifically time-related disciplines, enhance motor imagery and time perception abilities. Swimmers were more accurate and consistent in perceiving time when compared to runners, probably thanks to the sensory muffled environment that leads these athletes to be more focused on the perception of their internal rhythm.
