Implicit Learning of an Invariant: Just Say No

Following exposure to 30 four-digit numbers containing an invariant “3”, subjects are found falsely to recognize novel four-digit numbers containing this invariant (positives) in preference to novel numbers that do not contain the invariant (negatives). Despite this false recognition, they are generally unable to report the rule relating test positives to the positives seen during the learning phase. This finding has been taken to show implicit learning of a rule. Two experiments are reported here which show that it is not necessary to learn this rule in order to perform at above-chance levels on this test. Most of the effect can be explained in terms of the rejection of particularly distinctive test items that are more prevalent in the test negatives. This rejection appears to be mediated by knowledge that is potentially explicit as opposed to implicit, and we present tentative evidence that it is rule-based as opposed to analogic.     

Is Minority Stress in the Eye of the Beholder? A Test of Minority Stress Theory with Christians

Studies using minority stress theory have focused on the experiences of numerical and social power minorities, though majority individuals may also perceive themselves to be minorities. We explored minority stress theory among a sample of members of a numerically and socially dominant group: Christians in the USA. Perceiving oneself to be a member of a minority as a Christian was associated with stress indirectly via perceived experiences of faith-based discrimination (i.e., harassment due to being Christian). Being more open about one’s religion moderated the relationship between experiences of faith-based discrimination and stress, such that those who were open about their faith reported a stronger relationship between experiences of faith-based discrimination and stress. These findings indicate that perceptions of minority status are important to understanding stress and have implications for minority/majority dialogues.     

Comparing Business School Faculty Classification for Perceptions of Student Cheating

Faculty continue to address academic dishonesty in their classes. In this follow-up to an earlier study on general perceived faculty student cheating, using a sample of business school faculty, we compared three levels of faculty classification: full-time non-tenure track (NTT, n?=?86), full-time tenured/tenure-track (TT, n?=?66), and part-time adjuncts (A, n?=?71). Results showed that NTTs perceived higher levels for three different types of student cheating, i.e., paper-based, forbidden teamwork, and hiring someone to take an exam. In addition, NTTs were more likely to report a student for cheating. NTTs reported a higher course load and average class size, and average class size was positively related to all five types of cheating measured. Given the predicted increase in NTTs across all disciplines, making sure that all faculty, (but especially NTTs), have the resources needed to deter student cheating is important. All faculty have an obligation to hold students accountable for their behavior. Individual integrity is paramount; and it is what employers expect. Regardless of the chosen field or discipline, an employer’s expectations, in terms of character, is to hire individuals who possess a level of honesty that is above reproach. Addressing cheating is an obligation that all faculty need to address purposefully. Providing resources to help faculty address cheating is critical. Resources might include conflict resolution training to provide instructors with the necessary guidance so that they can better handle these difficult situations. This is important not only for the student while in school, but also for a university/college’s reputation.

Psychometric properties of reverse-scored items on the CES-D in a sample of ethnically diverse older adults

Reverse-scored items on assessment scales increase cognitive processing demands and may therefore lead to measurement problems for older adult respondents. In this study, the objective was to examine possible psychometric inadequacies of reverse-scored items on the Center for Epidemiologic Studies Depression Scale (CES-D) when used to assess ethnically diverse older adults. Using baseline data from a gerontologic clinical trial (n = 460), we tested the hypotheses that the reversed items on the CES-D (a) are less reliable than nonreversed items, (b) disproportionately lead to intraindividually atypical responses that are psychometrically problematic, and (c) evidence improved measurement properties when an imputation procedure based on the scale mean is used to replace atypical responses. In general, the results supported the hypotheses. Relative to nonreversed CES-D items, the 4 reversed items were less internally consistent, were associated with lower item-scale correlations, and were more often answered atypically at an intraindividual level. Further, the atypical responses were negatively correlated with responses to psychometrically sound nonreversed items that had similar content. The use of imputation to replace atypical responses enhanced the predictive validity of the set of reverse-scored items. Among older adult respondents, reverse-scored items are associated with measurement difficulties. It is recommended that appropriate correction procedures such as item readministration or statistical imputation be applied to reduce the difficulties.     

Flexible voices: Identity perception from variable vocal signals

Human voices are extremely variable: The same person can sound very different depending on whether they are speaking, laughing, shouting or whispering. In order to successfully recognise someone from their voice, a listener needs to be able to generalize across these different vocal signals (‘telling people together’). However, in most studies of voice-identity processing to date, the substantial within-person variability has been eliminated through the use of highly controlled stimuli, thus focussing on how we tell people apart. We argue that this obscures our understanding of voice-identity processing by controlling away an essential feature of vocal stimuli that may include diagnostic information. In this paper, we propose that we need to extend the focus of voice-identity research to account for both “telling people together” as well as “telling people apart.” That is, we must account for whether, and to what extent, listeners can overcome within-person variability to obtain a stable percept of person identity from vocal cues. To do this, our theoretical and methodological frameworks need to be adjusted to explicitly include the study of within-person variability.
