The COVID-19 pandemic has highlighted the need for further research evaluating the validity of conducting a battery of neuropsychological assessments virtually compared with face-to-face administration. Previous research has suggested that some neuropsychological assessments yield valid results when administered virtually, however, much of the previous research focused on older adults. To determine the validity of virtually administered neuropsychological tests, 28 healthy participants were assessed using a within-subjects, counter-balanced design. Participants completed a neuropsychological assessment battery covering tests of general intellectual functioning, memory and attention, executive functioning, language and information processing speed, as well as effort. There was no significant difference between face-to-face administration of the neuropsychological battery compared with virtual administration for the majority of the tests used. However, there were significant differences in the Colour Naming Task, with participants making fewer errors on the colour naming task and inhibition/switching task when administered virtually compared with face-to-face administration. There was also a significant age cohort effect in the inhibition/switching task. There was also a trending significant difference in mode of administration for the Verbal Fluency Task. Virtually administered neuropsychological assessments largely provide a valid alternative to face-to-face assessments; however, consideration must be given to test selection as well as the population of participants that are being assessed. Other important considerations must focus on preserving the security and integrity of test materials, as well as administration in a medico-legal setting. Future research should focus on validating assessments with specific patient populations and developing a neuropsychological assessment battery using information technology. 相似文献

The validity of a primate dominance hierarchy was examined in terms of its relationship to social interactions. Twelve social behaviors associated with dominance and aggression were recorded during 61 h of observation of six pigtail macaques (Macaca nemestrina). Of the 1,462 interactions recorded, 94.7% were oriented in the water dominance hierarchy in the direction that would be predicted on the basis of their ascribed functions. 相似文献

A series of five experiments examined the effects of irrelevant speech on proofreading and memory. Four of the experiments used a proofreading task and showed that the deleterious effects of irrelevant speech: (1) depend on the speech being meaningful, (2) are only present when the burden on short-term memory is low and (3) are manifested in a lower detection rate for non-contextual as opposed to contextual errors. Neither the spatial location of the speech (either in terms of spatial dispersion of sources or spatial movement of a single source) nor the intensity of the speech (in a range bounded by 50 dB(A) and 70 dB(A)) had any effect on proofreading. Late selection models of attention are favoured by the results in preference to models having arousal, short-term memory or early selection in attention as their basis. A final experiment showed serial recall for visual lists to be impaired by the presence of any speech-like sound (including reversed speech and speech in an unfamiliar language) which suggests a set of phenomena qualitatively different from those associated with proofreading. Throughout the article the practical consequences of the findings are emphasized. 相似文献

Consecutive counsellor trainee and client statements from 12 audiotaped assessment interviews were coded to operationalize empathy as a sequential variable. For each two statement sequence the speaking order (counsellor to client, client to counsellor) was also coded, and the resultant matrix analyzed via loglinear statistical procedures for categorical data. For the speaking order client to counsellor, three empathy sequences (empathy enhancing, empathy diverging, empathy commencing) were found to be significantly related to counselling effectiveness. For the speaking order counsellor to client, only one sequence(empathy diverging) was found to be significantly related to counselling effectiveness. Implications for counsellor training and future research are discussed. 相似文献

The effects of usage of eight verbal response modes by trainee counsellors during an initial interview were determined by reference to client-perceived rapport. Data on rapport were gathered via a standardized client's minute-by-minute ratings of his experience of rapport on a five-point scale during the interview. A total of ten counselling interviews were conducted, and data were examinedfor overall effects (i.e. during the interview as a whole) and minute-by-minute effects. Restatements, Minimal Encouragers and Verbosity were significantly dafferent in occurrence in high versus low rated interviews. Minute-by-minute data revealed that these overall differences were not consistent at all stages of the interviews. Implications for counsellor training are discussed. 相似文献

The disambiguation of threat/neutral homophones was investigated in high- and low-trait anxiety subjects who had been exposed
to either a positive or a negative mood manipulation procedure. Subjects were required first to spell each auditorily presented
word and second, to generate and speak a sentence using the word. Difference indices were calculated for the spelling and
the sentence usage data, i.e. the number of threat minus neutral interpretations. Examination of these indices revealed that
subjects exposed to the negative mood manipulation procedure produced relatively more threat than neutral interpretations
(for both spelling and sentence usage) than did subjects exposed to the positive mood manipulation procedure. Multiple regression
analyses revealed that both the trait anxiety and mood manipulation variables contributed significantly to the prediction
of the difference index on the spelling task. In the analysis of the use of homophones in sentences, only the mood manipulation
variable contributed significantly to the prediction of the difference index on the sentence usage task. 相似文献

In this study the authors investigated differences in the family environments of high- and low-trait angry college students. High-trait angry students described their family environments as significantly less cohesive, less emotionally expressive, more conflictual, and more disorganized than did their low-trait angry counterparts. Implications of the findings to the counseling of students with anger-related problems are discussed. 相似文献

A proximal-distal theoretical framework was developed to examine the multivariate roots of homophobia. Using data from a sample of 288 undergraduates who had participated in a computer-assisted panel study over a three-year period, the effects on homophobia of distal and proximal family factors (e. g., parental education and family environment), distal and proximal individual factors (e. g., personality constructs and current beliefs), and proximal individual-situational factors (e. g., acquaintance with homosexuals) were tested in regression analyses. Both analyses employing sets of variables varying in proximity to the homophobic attitude and hierarchical regression employing variables contributing significantly in each set supported the proposed framework. All sets predicted significantly when regressed separately on homophobia; the sets containing the distal factors contributed most weakly, and the sets containing the proximal factors contributed most strongly. In hierarchical regression analysis, this pattern maintained such that the incremental increase in r2 decreased with the addition of each more distal set, with the most distal factors failing to contribute significantly to the prediction. The importance of study findings for attitude change efforts is discussed. 相似文献

Eight children with developmental language impairment (LI) and eight age-, sex-, socioeconomic-status-, and I.Q.-matched controls were given tests of comprehension and expression of affective intent in spoken language and through facial expression. The LI children performed significantly more poorly than did controls in both comprehension and spontaneous expression of vocal affect. On tasks involving emotional facial expression, the opposite results were observed: The LI children were more dramatic in their expression of facial affect than were the controls. Children with language impairment appear to have a deficit in affective comprehension and expression that is modality-specific, i.e., limited to vocal affect. The heightened range of affective facial expression that they demonstrate may be a compensatory mechanism to offset their difficulties with vocal affect.This work was supported by grant 12-203 from the March of Dimes Birth Defects Foundation, and by NINDS grant NS22343 for the Center for the Study of the Neurological Basis of Language. 相似文献

The value of self-efficacy as a predictor of counselling skills performance in a graduate counselling class was evaluated with 31 trainee counsellors. Three measurements of self-efficacy were taken: before, midway through, and at the end of a microcounselling skills training programme which was taught over six weekly three-hour sessions. Although there was a wide distribution of self-efficacy reports, none of the estimates of grade were significantly positively associated with counselling skills. Implications for counsellor educators are discussed. 相似文献
