The racial identity and cultural orientation of Lumbee American Indian high school students

The uncertain and complex lineage of the Lumbee American Indian tribe has made the issue of identity of prime concern. The cultural identification, racial identification, bicultural competence, and perceived school environment for 103 Lumbee Indian high school students were examined in this study. Higher self-ratings on American Indian cultural competence and American Indian cultural identification than on White cultural competence and White cultural identification were found, and t-test comparisons revealed no gender differences on responses to the instruments. Analysis of variance was conducted to assess whether differences in perceived school environment could be attributed to cultural orientation. Rather than appearing assimilated, this generation of Lumbees tends to exhibit J. E. Helms's (1995b) Internalization identity status and an American Indian cultural orientation.     

Extending neuropsychological assessments into the primary mental ability space

A battery of 17 neuropsychological tests (including the CERAD battery) and 17 psychometric ability tests were administered to a sample of 499 participants of the Seattle Longitudinal study who had been given the psychometric ability tests seven and 14 years earlier. The neuropsychological tests were projected into a 5-factor psychometric ability space by means of extension analysis. The concurrent regressions of the neuropsychology tests on the psychometric ability tests were then used to estimate neuropsychology test scores from the psychometric ability tests administered in 1984, 1991 and 1998. Neuropsychologists then rated the study participants as either normal, suspect or cognitively impaired in 1998. Changes in estimated test scores were computed over seven and fourteen years. Significant odds ratios between normal and cognitively impaired groups were found for all neuropsychological tests over the proximal period and for most tests over the 14-year period. Similar findings occurred for the odds ratios between the normal and suspect groups for the most proximal 7-year changes.     

The causal role of theories of relationships: consequences for satisfaction and cognitive strategies

Two studies demonstrated the causal role of relationship theories in influencing relationship satisfaction and the processes affecting satisfaction. In both studies, participants were induced to hold either the soulmate or work-it-out theory. Feelings that one's partner was ideal (or not) were associated with relationship satisfaction more strongly for people induced to hold the soulmate theory than the work-it-out theory (Study 1). In Study 2, participants' beliefs about their relationships were threatened, and strategies for responding to this threat were assessed. Inducing people to hold the soulmate theory resulted in more relationship-enhancing cognitions if participants believed they were with the right person but more relationship-detracting cognitions if participants did not believe they were with the right person. These polarizing tendencies were enhanced under threat. In contrast, inducing people to hold a work-it-out theory produced almost no biased processing, leading people to process information similarly, regardless of their feelings about their partner.     

Touchscreen-enhanced visual learning in rats

The efficiency of traditional levers and of modern touchscreen technology for training rats on a computerized visual discrimination was studied in a series of observations. When compared with a lever-based discrimination procedure, the use of touchscreens supported the faster development of signal tracking behavior and acquisition of a two-stimulus simultaneous visual discrimination. It did not affect the final level of accuracy. Factors related to spatial proximity of the responses with the stimuli, sign-tracking, and increased ease of touchscreen motor responses were suggested as possible reasons for the touchscreen training advantage. This increased efficiency allows large numbers of animals to be tested quickly, a necessary requirement for studies involving genetic and physiological interventions.     

Contour grouping inside and outside of facial contexts

We examine how contours group in isolation compared with when they are embedded in face-like contexts. As previously shown, contours that seem to group by phenomenological observation also show powerful effects on task performance: with contours that group, selective attention to one while ignoring another is poor (as indexed by Garner Interference (GI), but not Stroop Interference), whereas divided attention across contours is good. With contours that do not group, however, the reverse happens. Here we test pairs of curved lines (parentheses) displayed either in isolation or within contexts including cartoon faces, where these curves may serve as mouths or eyebrows. The results with isolated contours replicate previous findings of poor selective attention, but within face-like contexts the same contours showed nearly perfect selective attention (i.e., zero GI). Thus, contour grouping was weaker inside than outside of faces, a finding that contrasts with the widely-held belief that faces are processed configurally, not by local features.     

MMPI-2 L + K and L + K - F indexes of underreporting: normative and desirable responding

Norms based on the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) normative sample are provided for the L + K and L + K - F indexes of underreporting and defensiveness. Index scores produced by consistently desirable responding, which was guided by desirability ratings of the MMPI-2 items, also are provided and compared with scores produced by underreporting in other studies. The indexes correlate highly with other measures of underreporting in both normative and clinical samples. The L and K scales assess different types of underreporting and should be interpreted separately as well as in combination. The L scale can be elevated by undesirable responding or random responding in addition to desirable responding.     

Ethical? Toward whom?

Comments on the original article, "Nonrational processes in ethical decision making" by M. D. Rogerson et al (see record 2011-19198-001). Among the many insightful points made by Rogerson, Gottlieb, Handelsman, Knapp, and Younggren (October 2011) regarding nonrational processes in ethical decision making, one deserves further explication: Many of psychologists' ethical decisions lead to actions done to someone. Unfortunately, frameworks and models of ethical decision making frequently neglect this fact by implying that the decisions happen in the abstract, but in truth, these decisions often affect a specific recipient. Importantly, the characteristics of that specific recipient, especially as perceived by the psychologist, can have a powerful impact on the process of ethical decision making (Caughron et al., 2011). It would be wise to add such a hypothetical to the list of specific questions that Rogerson et al recommended psychologists ask themselves: Would I make the same ethical decision if the person(s) toward whom the decision is directed had different characteristics?     

Grouping and emergent features in vision: toward a theory of basic Gestalts

Gestalt phenomena are often so powerful that mere demonstrations can confirm their existence, but Gestalts have proven hard to define and measure. Here we outline a theory of basic Gestalts (TBG) that defines Gestalts as emergent features (EFs). The logic relies on discovering wholes that are more discriminable than are the parts from which they are built. These wholes contain EFs that can act as basic features in human vision. As context is added to a visual stimulus, a hierarchy of EFs appears. Starting with a single dot and adding a second yields the first two potential EFs: the proximity (distance) and orientation (angle) between the two dots. A third dot introduces two more potential EFs: symmetry and linearity; a fourth dot produces surroundedness. This hierarchy may extend to collinearity, parallelism, closure, and more. We use the magnitude of Configural Superiority Effects to measure the salience of EFs on a common scale, potentially letting us compare the strengths of various grouping principles. TBG appears promising, with our initial experiments establishing and quantifying at least three basic EFs in human vision.     

Is depression the past tense of anxiety? An empirical study of the temporal distinction

It has long been recognised that depression and anxiety share a common core of negative affect, but research on similarities and differences between these two emotions is growing. The focus of the current study was on whether the timing of a triggering event can determine whether the dominant emotional reaction is depression or anxiety. It was hypothesised that aversive events in the past would elicit more depression than anxiety, whereas the same aversive events in the future would elicit more anxiety than depression. We created temporally varied versions of vignettes describing aversive events occurring at either time, and asked participants to rate the extent to which the events would elicit feelings of depression or anxiety. Results indicated that adverse past events elicited much higher ratings of anticipated depression and adverse future events elicited much higher ratings of anticipated anxiety. Implications for understanding these two emotions and depressive and anxiety disorders are discussed.
