Methods for the capture, maintenance, taming, and behavioral testing of wild-born muskrats(Ondatra zibethicus) are described. The muskrat is simple and inexpensive to maintain in the laboratory and seems suitable for behavioral research. 相似文献

Two correlational studies and related factor analyses (N = 70. N = 76) were addressed to four psychometric hypotheses derived from the imagery-desensitization literature. Consistent with prior research, self-ratings of imaginal vividness correlated moderately positively across sense modalities. Vividness ratings were inconsistently related to imagery control scores however. The question of the extent to which imagery scales reflect the influences of response sets and general intelligence has been raised recently in this journal Behav. Res. and Therapy 10, 137 (1972). Acquiescence tendency does not appear to influence imagery questionnaire results and there is only a small contamination effect from the social desirability response style, thus suggesting that these questionnaires are substantially free of response bias invalidation. Verbal intelligence is unrelated to researched imaginal attributes, as measured by self-report scales and several behavioral measures, including location memory and spatial visualization. These behavioral measures, in turn, do not correlate with ratings of imagery characteristics, a finding in accord with previous literature. Although self-report imagery questionnaires stand up better to psychometric scrutiny than might have been expected, and thus prior research employing them cannot be dismissed summarily, it is argued that these questionnaires may not tap the variables most relevant to desensitization outcome or mediation. The necessity of using state rather than trait measures, and of relating these to physiological indices, is highlighted. 相似文献

The present research examined relationships involving marital conflict, parenting, and toddler conduct problems. Sixty mother-toddler dyads (30 boys and 30 girls) participated as subjects. Mothers completed measures of general marital satisfaction, overt marital conflict, and toddler conduct problems. Maternal parenting and toddler deviance were assessed during a laboratory observation. Marital conflict was positively correlated with observations of toddler deviance and maternal reports of conduct problems. Marital conflict also correlated positively with the frequency of maternal disapproval statements directed toward sons' misbehaviors and was correlated negatively with the ratio of disapproval statements to daughters' misbehaviors. The present results indicate that marital conflict is associated with toddler conduct problems. The results also suggest the importance of examining parenting practices and child characteristics that may mediate the relationship between marital conflict and child behavior problems.This research was supported, in part by a Sigma XI grant to the second author. 相似文献

The construction of word meanings in a discourse context was conceptualized as a process of sense activation, sense selection, and sense elaboration. In three experiments, subjects read texts presented by a rapid serial visual procedure and performed a lexical decision on visually presented targets that followed ambiguous prime words. When the target was a word, it was either an associate of the prime word, a probable inference suggested by the discourse, or an unrelated word. For associates, lexical decisions that related to either the appropriate or the inappropriate sense of the ambiguous word were generally facilitated at short (200-400 msec) prime-target stimulus onset asynchronies (SOAs). At longer SOAs, responses were faster to appropriate than to inappropriate associates. For the thematic inferences, there was no difference between these (appropriate) inferences and (inappropriate) control words at short SOAs. At long SOAs (1,000 and 1,500 msec), however, inference words were facilitated. The results are interpreted as consistent with a model of lexical processing in which sense activation functions independently of context. Discourse context effects, whether on sense selection (suppression of inappropriate associates) or on sense elaboration (creation of inferences), are seen as postlexical. 相似文献

Though the theoretical and clinical ramifications of attribution of primary responsibility to mothers for child rearing have been discussed extensively, there is little empirical data in this area. In the present study a sample of parents rated several child-rearing behaviors in terms of ideal maternal and paternal responsibility. Mothers were attributed primary responsibility for the largest proportion of behaviors, fathers for the smallest, and an intermediate number of items were rated as parentally shared. In addition, item analysis indicated a relationship between the directionality of responsibility attribution and traditional sex-role stereotypes. Implications for patterns of intrafamilial blame and clinical intervention are discussed. 相似文献

The McCarthy Scales of Children's Abilities (MSCA) was administered to 200 children, 100 males and 100 females, with a mean chronological age of 3–9. The results were subjected to factor analysis to determine the validity of MSCA alignment into six distinct indexes, or factors, and to determine if there were sex differences in factors produced by the MSCA. A general (“g”) factor was derived for both females and males. Specific factors (Abstract Verbal Reasoning and Remote Verbal Memory) were derived for the female sample. Two specific factors (Sequential Memory and Nonverbal Cognition) were derived for the male sample. Only the “g” factors derived for male, female, and total samples corresponded to the General Cognitive Index (GCI) used in the MSCA. The results suggested that clinical interpretation of the MSCA should be made cautiously for both normal and exceptional children until further exploration of the construct validity and sex differences in the MSCA can be conducted. 相似文献

In previous studies, we have found that the accuracy in judging collinearity of lines or dots varies considerably from one subject to another as a function of the relative angle of the stimulus elements. A model of errors generally shows large excursions across several subranges of angular position. These do not appear to be motor errors, at least not ones that are well separated from perceptual mechanisms. The errors are most likely generated at primary visual cortex, or beyond. We examined and modeled accuracy in judging collinearity of dot pairs, varying the angular position of the dots through 360 degrees, the distance between the dots (stimulus span), and the distance at which the subject was required to respond (response span). Subjects manifested idiosyncratic profiles of error across angular positions, as reported previously. But across the tested range of spans, from 4 to 8 deg, the errors tended to be the same, irrespective of stimulus or response span. This suggests that the judgments are based on a radial (angular) measure of spatial position. We discuss these results in the context of proposals that the brain maps spatial position using rotation coordinates. These new data are consistent with the hypothesis that subjects use the z-axis coordinates as a mental protractor for judging angular position and collinearity. 相似文献

The present study investigated the relationship between similarity of self-reported biodata and recruiter ratings of applicant job preparedness. Subjects included 108 dyads, each composed of a corporate recruiter and a university student applying for a position posted by the recruiter's company. Because no effect of similarity bias was found, the results challenged the generalizability of previous laboratory study findings. The question of possible experimental design artifacts in prior field studies was also raised. 相似文献

A production task analogue of the traditional multiple choice trait checklist method was used to investigate stereotypes. Subjects were asked to supply rather than to select the most characteristic attributes of specified social groups. In a departure from tradition, stability of the content of stereotypes was analysed for personal stereotypes held by individuals rather than for social stereotypes shared by a cultural group. In contrast to the widely held belief that social stereotypes are fixed and unchanging, personal stereotypes were found to be only moderately stable over time. Only about two-fifths of the most characteristic attributes were duplicated in sessions separated by one week, and only about one-fifth of the most Characteristic attributes were duplicated in sessions separated by one-month or two-month intervals. Findings also supported the notion that general attributes, most characteristic attributes, and least characteristic attributes of a social category are not totally redundant and are represented quasi-independently in memory. Only about half of the most characteristic responses had also occurred on free response protocols and over half of the least characteristic responses tended not to be polar opposites of the most characteristic responses. It was the case, however, that with a production analogue of the multiple-choice trait checklist, trait-adjectives were the most frequent class of person information and accounted for between 50 and 60 per cent of the responses. However, eleven other classes of person information also occurred. Empirical results were applied toward a reexamination of the concepts of stereotype (data structure for the most characteristic attributes of a social group) and stereotyping (rigid procedures for processing data structures) and to a conceptual analysis of how stereotypes and social categories are structurally related. 相似文献
