Examined the chronological and statistical relations among onsets of psychopathology, alcohol and cannabis use, and substance-related problem psychopathology, alcohol and cannabis use, and substance-related problems from late childhood through early adolescence in boys of fathers with substance use disorder (SUD; high average risk: n = 177) and without SUD (low average risk: n = 203) using survival analysis. Proportional hazard models indicated that antisocial disorders were predicted by risk group and mediated the observed relation between risk group and substance-related problems. Negative affect disorders were predicted by risk group but did not predict substance involvement in early adolescence. Results support a model in which paternal SUD predisposes to increased antisocial and negative affect disorders in boys, and antisocial disorders lead to substance-related problems in early adolescence. 相似文献

Findings are presented from a qualitative study exploring young people's perceptions that are relevant to the provision of a youth counselling service. Data were collected through individual and group interviews with a sample of 42 young people, most of whom were between 15 and 18 years old. The data were analysed using a grounded theory approach. Two key categories emerged from this analysis: factors which hinder young people's willingness to seek counselling, and factors which would encourage young people to make use of counselling. Specific themes within these categories are explored, and the wider implications of findings from the study are discussed. 相似文献

Six normally capable adults first learned three conditional relations in each of two prospective equivalence classes via match-to-sample training with figures as conditional (sample) and discriminative (comparison) stimuli. Then one trained conditional relation in each prospective class was brought under the control of contextual stimuli, two dictated nonsense syllables. Test performances indicated the emergence of untrained conditional relations, and therefore two equivalence classes, that were conditional on the contextual stimuli. These tests involved untrained combinations of contextual stimuli and stimuli in conditional relations, suggesting that the contextual stimuli functioned independently to control conditional relations rather than forming compound stimuli with samples and comparisons in training. Next, two novel figures were made equivalent to each of the original dictated contextual stimuli by match-to-sample training and testing. On subsequent tests, all subjects demonstrated transfer of conditional control of untrained conditional relations from the original auditory contextual stimuli to equivalent visual stimuli. These outcomes further supported the conclusion that the contextual stimuli exerted true conditional control over conditional relations in the equivalence classes and were not merely elements of compound stimuli. 相似文献

Influences of acculturation and musical sophistication on music perception were examined. Judgments for mistuning were obtained for Ss differing in musical sophistication who listened to a melody that was based on interval patterns from Western and Javanese musical scales. Less musically sophisticated Ss' judgments were better for Western than Javanese patterns. Musicians' thresholds did not differ across Western and Javanese patterns. Differences in judgments across scales are accountable to acculturation through listening exposure and musical sophistication gained through formal experience. 相似文献

This experiment sought to determine whether previously found metric violations of additive expectancy-value models C.F. J. C. Shanteau, Journal of Experimental Psychology, 1974, 103, 680–691; J. G. Lynch and J. L. Cohen, Journal of Personality and Social Psychology, 1978, 36, 1138–1151) were attributable to the inappropriateness of these models or to nonlinearities in the relationship between numerical ratings and underlying psychological impressions. Undergraduate participants performed two tasks employing the same experimental stimuli. In the first task, they rated the subjective values of hypothetical bets, judged separately and in combination. In the second task, they made pairwise comparisons of the same bets in terms of preference. The use of the same experimental stimuli in both tasks allowed a test of alternative models of utility judgment through application of the criterion of scale convergence (M. H. Birnbaum & C. T. Veit, Perception and Psychophysics, 1974, 15, 7–15). Results suggested that the additive expectancy-value model of judgments of the utilities of combinations of outcomes should be replaced by a weighted averaging rule in which the weight given to the value of each outcome in the averaging process is greater when this value is negative and extreme than when it is neutral. 相似文献

An interface, controlled by a Z-80 central processor, that plugs into the PET microcomputer’s IEEE-488 port is described. This interface is capable of controlling 48 separate 28-V dc output signals, six of which are high current. Sixteen inputs (switch closures) can be accepted by the interface. Data tagged with real-time information are output automatically to cassette tape in PET format. This PET interface system is designed to accommodate a single experimental station. 相似文献

Studies using the Thought Control Questionnaire (TCQ; Wells & Davies, 1994) suggest that the tendency to use self-punishment (e.g., shouting at oneself) in order to control unpleasant internal experiences (e.g., cognitive and emotional) is associated with psychopathology. To evaluate the role of self-punishment in borderline personality disorder (BPD), we first examined whether TCQ scales, including Self-Punishment, were different among adults with BPD (n = 31) when compared to those with other personality disorders (OPD; n = 24), elevated symptoms of major depressive disorder (MDD; n = 24), and healthy controls (n = 105). Findings indicated that Self-Punishment was elevated in the BPD group relative to other groups. Next, Self-Punishment was examined as a potential mediator in the relationship between negative affectivity and BPD symptom severity in all participants. Results indicated that Self-Punishment did not mediate this relationship, but did account for significant variance in BPD symptoms over and above negative affectivity. Implications and future research directions are discussed. 相似文献

Individuals with borderline personality disorder (BPD) have been hypothesized to exhibit significant problems associated with emotional sensitivity. The current study examined emotional sensitivity (i.e., low threshold for recognition of emotional stimuli) in BPD by comparing 20 individuals with BPD and 20 normal controls on their accuracy in identifying emotional expressions. Results demonstrated that, as facial expressions morphed from neutral to maximum intensity, participants with BPD correctly identified facial affect at an earlier stage than did healthy controls. Participants with BPD were more sensitive than healthy controls in identifying emotional expressions in general, regardless of valence. These findings could not be explained by participants with BPD responding faster with more errors. Overall, results appear to support the contention that heightened emotional sensitivity may be a core feature of BPD. 相似文献
