Family Interaction Patterns as Predictors of Vocational Identity and Career Decision-Making Self-Efficacy 总被引:2,自引:0,他引:2

The present study explored the relations of perceived family-of-origin interaction patterns (e.g., quality of family relationships, family-supported goal orientations, and degree of control and organization in the family) to vocational identity and career decision-making self-efficacy. A sample of 210 college students completed family-of-origin and vocational self-report measures. Using standard multiple regression analyses, significant variance was accounted for in vocational identity scores by achievement orientation in the family. Significant variance in career decision-making self-efficacy scores was accounted for by a number of family variables including achievement, intellectual-cultural, and moral-religious emphasis orientations and degree of family conflict and expressiveness. The findings suggest that family-of-origin interaction patterns may play small, yet significant roles in the formulation of clear and stable career goals and the promotion of self-confidence in regard to completing career planning activities. These findings warrant further empirical examination of the family systems approach to young adult career development. 相似文献

Typical patterns of general subjective well-being (SWB) were searched for in a representative longitudinal sample of Swedish
women (N = 272) at age 43 and 49. Cluster analysis at each age separately resulted in a six-cluster solution at both ages. The two
solutions were similar, indicating structural stability across 6 years. Five of the six clusters also showed significant individual
stability. Among these clusters, a generalized positive typical pattern and two generalized negative typical patterns were
found, one characterized by very high negative affect and one characterized by very low global life satisfaction. A cluster
characterized by above average positive and negative affect was also found as well as one characterized by low positive affect.
A strong relationship was found between membership in an extreme cluster and the values in certain SWB-related variables,
supporting the validity of the typical patterns found. Further, it was shown that cluster membership contributed to the prediction
of some validation variables above the prediction achieved by using only SWB components entered as continuous variables, suggesting
the presence of interactions and nonlinearities in the SWB area. 相似文献

This study uses data from the longitudinal research program Individual Development and Adaptation, where an entire school‐grade cohort of children in a middle‐size Swedish city (n~1.300) has been followed from ages 10 to 43 and 48 for women and men, respectively. Our findings indicate that the patterns of offending across the life‐course differ between genders, where males seem to initiate their offending earlier than females. Further, there are very few women on a persistent offending‐trajectory. Focusing on precursors to as well as consequences of offending as indexed in official registers, our results indicate that individuals in the persistent offender group have the most pronounced adjustment problems in school‐ as well as in middle age. Individual characteristics and behaviors (e.g., aggression, hyperactivity, antisocial behavior) vary systematically between individuals with different developmental offending patterns. The combination of an unstable upbringing and own antisocial behavior seems to be especially predictive for criminality. For persistent offenders, the prevalence of alcohol and psychiatric problems at adult age is high for males and extremely high for females (nine out of ten and six out of ten for each of the two problem types for females). Further, the importance for adjustment of the two‐dimensional variation in the number of crimes committed during adolescence and adult age seems to have been surprisingly well captured by the “crude” division into the four offender groups that were used.

Sign- versus goal-tracking: effects of conditioned-stimulus-to-unconditioned-stimulus distance. 总被引:2,自引:0,他引:2 下载免费PDF全文
Three pigeons were exposed sequentially across experimental phases to five different distances between the conditioned stimulus and the site of the unconditioned stimulus in a sign-/goal-tracking procedure. A computer-controlled tracking system provided a continuous record of the bird's position by continuously monitoring the location of the bird's head in three-dimensional space. It was found that birds sign-tracked (i.e., approached the conditioned stimulus) when the conditioned stimulus was closest to the site of the unconditioned stimulus, goal-tracked (i.e., approached the site of the unconditioned stimulus in the presence of the conditioned stimulus) when the conditioned stimulus was farthest from the site of the unconditioned stimulus, and engaged in both sign- and goal-tracking (or something intermediate) at intermediate conditioned-stimulus-to-unconditioned-stimulus distances. When both sign- and goal-tracking occurred, the former tended to occur in the first half and the latter in the second half of the interval in which the conditioned stimulus was present. The results suggest (a) whether sign- or goal-tracking (or both) occurs is a function of the distance of the conditioned stimulus from the site of the unconditioned stimulus, (b) the fact that pigeons but not rats have been found to sign-track consistently throughout the duration of the conditioned stimulus may be due to quantitatively rather than qualitatively different effects of conditioned-stimulus-to-unconditioned-stimulus distance across species (i.e., a "short" conditioned-stimulus-to-unconditioned-stimulus distance for a pigeon may be a "long" one for a rat), and (c) sign- and goal-tracking may be competing behavioral tendencies that can (e.g., at intermediate conditioned-stimulus-to-unconditioned-stimulus distances) cancel each other out. The findings lend support to theories that specify an interaction between phylogenetic and reinforcement variables in determining whether sign- or goal-tracking will occur in any given experimental preparation. 相似文献

Pigeons and rats responded on fixed-ratio schedules with requirements ranging from 5 to 120 responses. Consistent with past results from several schedules and procedures, responding usually changed systematically within experimental sessions. The within-session changes were usually larger and were less symmetrical around the middle of the session for schedules that provided higher, rather than lower, rates of reinforcement. These results suggest that similar variables contribute to within-session changes in responding under different schedules. When an economic demand function was fit to the data, the intensity and elasticity of demand for food and the percentage of the variance accounted for decreased within sessions, although the trend for elasticity did not reach statistical significance for pigeons. These results suggest that relatively short sessions should be used to study economic demand in open economies and that demand may differ at different times in a session and in sessions of different lengths. Within-session changes in intensity, but not necessarily elasticity, of demand are consistent with behavioral economic theories. 相似文献

Mothers and fathers who experience parenting stress are more likely to show symptoms of distress, such as elevated levels of anxiety and/or depression. Identifying the buffering or exacerbating factors that might moderate the association between parenting stress and general distress can help inform theoretical models aimed at better understanding the reality faced by parents during challenging times, as well as improve intervention strategies. The objective of this study was to examine whether coparenting quality plays a moderating role in the association between parenting stress and general distress in parents of children in middle childhood. Eighty-one couples were asked to complete questionnaires pertaining to their levels of parenting stress, the quality of their coparenting relationship, and their symptoms of distress. Using an Actor–Partner Interdependence Moderation Model, our results revealed that elevated levels of parenting stress were associated with elevated levels of general distress, whereas higher scores of coparenting quality were associated with fewer symptoms of distress. Our results also showed a moderating role for coparenting quality in the association between actor parenting stress and actor/partner distress. These findings highlight the importance of pursuing the investigation of dyadic effects within personal relationships. 相似文献

Three pigeons were exposed to 1-hr and 4-hr sessions during which they earned food under a fixed-ratio 50 schedule of reinforcement while obtaining additional food according to either a variable-interval or a variable-time schedule. Postsession food was provided after the 1-hr sessions. The frequency of the variable-interval and variable-time food presentations was varied under the two session durations. The various combinations of within-session earned and unearned food, as well as the postsession food, defined conditions on the open-to-closed economy continuum. Key pecks tended to increase as the frequency of either variable-interval or variable-time food decreased. An economic-continuum analysis based on an independence quotient as a measure of response-reinforcer independence is presented to account for the effects. 相似文献

Operant conditioning of behavioral variability using a percentile reinforcement schedule. 总被引:3,自引:3,他引:0
A Machado 《Journal of the experimental analysis of behavior》1989,52(2):155-166
The present investigation developed and tested a new percentile reinforcement schedule suited to study pattern variability, whose main feature was the relative dissociation it provided between the variability requirement defining criterional responses and overall probability of reinforcement. In a discrete-trials procedure, pigeons produced patterns of four pecks on two response keys. If the pattern emitted on the current trial differed from the N preceding patterns, reinforcement was delivered with probability mu. The schedule continuously adjusted the criterion N such that the probability of a criterional response, estimated from the subject's recent behavior, was always constant. In these circumstances, the criterion corresponded to an invariant percentile in the distribution of recent responses. Using a between-subjects design, Experiment 1 manipulated the variability requirement--the percentile--while keeping overall reinforcement probability constant. The degree of variability varied directly with the requirement. In addition, an inverse relationship existed between the requirement and within-group variance. Experiment 2 manipulated probability of reinforcement while maintaining the variability requirement constant. No consistent relationship was found between variability and reinforcement probability. A tentative hypothesis was advanced ascribing the operant conditioning of behavioral variability to a process of probability-dependent selection. 相似文献

Spatiotemporal patterns of behavior produced by variable-interval schedules of reinforcement 总被引:6,自引:6,他引:0 下载免费PDF全文
Pear JJ 《Journal of the experimental analysis of behavior》1985,44(2):217-231
The spatiotemporal patterns of behavior exhibited by two pigeons during a variable-interval 15-second schedule of food reinforcement, a variable-interval 5-minute schedule, and then extinction of key pecking were recorded using an apparatus that continuously tracked the position of the bird in the experimental chamber. The variable-interval 15-second schedule produced a close-to-key pattern between reinforcements with two types of regular excursions from the region of the key frequently occurring after reinforcement. Subsequent exposure to the variable-interval 5-minute schedule produced more extended and extremely regular patterns between responses. Reinstatement of the variable-interval 15-second schedule reestablished the close-to-key pattern with regular excursions frequently occurring after reinforcement. During extinction the spatiotemporal patterns that had developed during the variable-interval 5-minute schedule reappeared and gradually dissipated. These patterns may have been a form of superstitious behavior. 相似文献
