The relationship between gender,perceived career barriers,and occupational aspirations

The relationships between college student gender, perceived career barriers, and occupational aspirations were examined. Participants were 314 students located in the southeastern United States. Overall, college women reported higher levels of occupational aspirations than college men. While occupational aspirations were not correlated with perceived career barriers for women or men, women reported anticipating more barriers to their career advancement than their male peers. Perceived career barriers and the interaction between gender and perceived career barriers predicted occupational aspirations after controlling for gender, socioeconomic status, ethnicity, and year in school. The relationship between occupational aspirations and the interaction between gender and perceived career barriers in college‐age adults enhances our understanding of occupational aspirations.

Testing the validity of conflict drift-diffusion models for use in estimating cognitive processes: A parameter-recovery study

Researchers and clinicians are interested in estimating individual differences in the ability to process conflicting information. Conflict processing is typically assessed by comparing behavioral measures like RTs or error rates from conflict tasks. However, these measures are hard to interpret because they can be influenced by additional processes like response caution or bias. This limitation can be circumvented by employing cognitive models to decompose behavioral data into components of underlying decision processes, providing better specificity for investigating individual differences. A new class of drift-diffusion models has been developed for conflict tasks, presenting a potential tool to improve analysis of individual differences in conflict processing. However, measures from these models have not been validated for use in experiments with limited data collection. The present study assessed the validity of these models with a parameter-recovery study to determine whether and under what circumstances the models provide valid measures of cognitive processing. Three models were tested: the dual-stage two-phase model (Hübner, Steinhauser, & Lehle, Psychological Review, 117(3), 759–784, 2010), the shrinking spotlight model (White, Ratcliff, & Starns, Cognitive Psychology, 63(4), 210–238, 2011), and the diffusion model for conflict tasks (Ulrich, Schröter, Leuthold, & Birngruber, Cogntive Psychology, 78, 148–174, 2015). The validity of the model parameters was assessed using different methods of fitting the data and different numbers of trials. The results show that each model has limitations in recovering valid parameters, but they can be mitigated by adding constraints to the model. Practical recommendations are provided for when and how each model can be used to analyze data and provide measures of processing in conflict tasks.     

The Ecological Validity of Delay Aversion and Response Inhibition as Measures of Impulsivity in AD/HD: A Supplement to the NIMH Multimodal Treatment Study of AD/HD

Impulsivity is a primary symptom of the combined type of Attention Deficit/Hyperactivity Disorder (AD/HD). The Stop Signal Paradigm is premised upon a primary deficit in inhibitory control in AD/HD, whereas the Delay Aversion Hypothesis, by contrast, conceptualizes impulsivity in AD/HD, not as an inability to inhibit a response, but rather as a choice to avoid delay. This study compared the ecological validity of the Stop Signal Task (SST) and Choice-Delay Task (C-DT) measure of delay aversion, with respect to their relative utility in discriminating AD/HD children from normal control participants, and their correlations with classroom observations and with ratings of impulsivity and other core AD/HD symptoms on the Conners and SNAP-IV checklists. The tasks exhibited modest discriminant validity when used individually and excellent discriminant validity when used in combination. The C-DT correlated with teacher ratings of impulsivity, hyperactivity, and conduct problems, and with observations of gross motor activity, physical aggression, and an AD/HD composite score. The SST correlated with the observations only. These results suggest that delay aversion is associated with a broad range of AD/HD characteristics whereas inhibitory failure seems to tap a more discrete dimension of executive control     

Balancing cognitive demands: control adjustments in the stop-signal paradigm

Cognitive control enables flexible interaction with a dynamic environment. In 2 experiments, the authors investigated control adjustments in the stop-signal paradigm, a procedure that requires balancing speed (going) and caution (stopping) in a dual-task environment. Focusing on the slowing of go reaction times after stop signals, the authors tested 5 competing hypotheses for post-stop-signal adjustments: goal priority, error detection, conflict monitoring, surprise, and memory. Reaction times increased after both successful and failed inhibition, consistent with the goal priority hypothesis and inconsistent with the error detection and conflict hypotheses. Post-stop-signal slowing was greater if the go task stimulus repeated on consecutive trials, suggesting a contribution of memory. We also found evidence for slowing based on more than the immediately preceding stop signal. Post-stop-signal slowing was greater when stop signals occurred more frequently (Experiment 1), inconsistent with the surprise hypothesis, and when inhibition failed more frequently (Experiment 2). This suggests that more global manipulations encompassing many trials affect post-stop-signal adjustments.     

Post-stop-signal slowing: strategies dominate reflexes and implicit learning

Control adjustments are necessary to balance competing cognitive demands. One task that is well-suited to explore control adjustments is the stop-signal paradigm, in which subjects must balance initiation and inhibition. One common adjustment in the stop-signal paradigm is post-stop-signal slowing. Existing models of sequential adjustments in the stop-signal paradigm suggest that post-stop-signal slowing may be based solely on the events of the previous trial, suggesting that post-stop-signal slowing is a reflexive byproduct of a stop signal. Alternatively, post-stop-signal slowing could be the result of implicit learning or strategic adjustment. The authors report three experiments that manipulated the probability of stop trial repetition and found that these contingencies eliminate, reverse, or greatly increase post-stop-signal slowing. When the contingency was not instructed or cued, modest adjustments of post-stop-signal slowing occurred, suggesting implicit learning. When the contingency was cued, performance adjustments occurred on the next trial, suggesting that strategies dominated post-stop-signal slowing. These results show that post-stop-signal slowing is not a reflexive byproduct of the stop signal. The large changes in strategy accompany large changes in task factors, suggesting that the modest post-stop-signal slowing usually observed may be a result of the relatively static task environment that does not encourage large strategic changes.     

Post-stop-signal adjustments: inhibition improves subsequent inhibition

Performance in the stop-signal paradigm involves a balance between going and stopping, and one way that this balance is struck is through shifting priority away from the go task, slowing responses after a stop signal, and improving the probability of inhibition. In 6 experiments, the authors tested whether there is a corresponding shift in priority toward the stop task, speeding reaction time to the stop signal. Consistent with this hypothesis, stop-signal reaction time (SSRT) decreased on the trial immediately following a stop signal in each experiment. Experiments 2-4 used 2 very different stop signals within a modality, and stopping improved when the stop stimulus repeated and alternated. Experiments 5 and 6 presented stop signals in different modalities and showed that SSRT improved only when the stop stimulus repeated within a modality. These results demonstrate within-modality post-stop-signal speeding of response inhibition.     

What skilled typists don’t know about the QWERTY keyboard

We conducted four experiments to investigate skilled typists’ explicit knowledge of the locations of keys on the QWERTY keyboard, with three procedures: free recall (Exp.?1), cued recall (Exp.?2), and recognition (Exp.?3). We found that skilled typists’ explicit knowledge of key locations is incomplete and inaccurate. The findings are consistent with theories of skilled performance and automaticity that associate implicit knowledge with skilled performance and explicit knowledge with novice performance. In Experiment?4, we investigated whether novice typists acquire more complete explicit knowledge of key locations when learning to touch-type. We had skilled QWERTY typists complete a Dvorak touch-typing tutorial. We then tested their explicit knowledge of the Dvorak and QWERTY key locations with the free recall task. We found no difference in explicit knowledge of the two keyboards, suggesting that typists know little about key locations on the keyboard, whether they are exposed to the keyboard for 2 h or 12 years.     

Attitudes Towards Potentially Carrying the FMR1 Premutation: Before vs After Testing of Non-Carrier Females with Diminished Ovarian Reserve

Diminished ovarian reserve (DOR) and premature ovarian failure are associated with elevated FMR1 CGG repeat alleles. We assessed pretest attitudes about potentially carrying the FMR1 premutation (FXP) (>55 CGG repeats) among reproductive age women compared with attitudes after learning their non-carrier status. Ninety-two women with DOR, regular menses and no family history of Fragile X Syndrome underwent FMR1 testing and completed attitudinal questionnaires before (T1) and 3 months after learning the test results (T2). The analysis utilized signed rank tests and α?=?0.05. Very few women thought they were likely to have a FXP (6.6 %). More participants thought FMR1 premutations were “serious” at T2 (62.9 %) than at T1 (46.1 %, p?p?相似文献   

Informant reports add incrementally to the understanding of the perfectionism–depression connection: Evidence from a prospective longitudinal study

Perfectionism is a putative risk factor for depressive symptoms. However, most research in this area uses cross-sectional designs (which fail to address temporal precedence) and mono-source designs (which are influenced by various biases). The present study overcomes these limitations by using a novel design involving both self- and informant reports of self-critical perfectionism (i.e., negative reactions to perceived failures, concern over others’ criticism and expectations, doubts about performance abilities, and intense self-rebuke). It was hypothesized that self- and informant reports of self-critical perfectionism would correlate moderately and that self- and informant reports of self-critical perfectionism would predict increases in depressive symptoms over time. A sample of 155 target participants and 588 informants was recruited and studied using a prospective longitudinal design. All study hypotheses were supported, including evidence that self- and informant reports of self-critical perfectionism each add incrementally to the understanding of the self-critical perfectionism–depressive symptoms connection. Informant reports may provide a more complete picture of the self-critical perfectionist and her or his vulnerability to depressive symptoms.
