Dimensions of acculturation: associations with health risk behaviors among college students from immigrant families

In the present study, we examined a bidimensional model of acculturation (which includes both heritage and U.S. practices, values, and identifications) in relation to hazardous alcohol use, illicit drug use, unsafe sexual behavior, and impaired driving. A sample of 3,251 first- and second-generation immigrant students from 30 U.S. colleges and universities completed measures of behavioral acculturation; cultural values (individualism, collectivism, and self-construal); ethnic and U.S. identity; and patterns of alcohol and drug use, engagement in potentially unsafe sexual activities, and driving while (or riding with a driver who was) intoxicated. Results indicate that heritage practices and collectivist values were generally protective against health risk behaviors, with collectivist values most strongly and consistently protective. Nonetheless, heritage identifications were positively associated with sexual risk taking for Hispanics. U.S. practices, values, and identifications were not consistently related to risk behavior participation. Results are discussed in terms of bidimensional approaches to acculturation, the immigrant paradox, and implications for counseling practice.     

Voices of Experienced Meditators: The Impact of Meditation Practice on Intimate Relationships

Using a qualitative methodology, we explored advanced meditators’ understandings of the effect of the meditation traits on close relationships. Seven participants were interviewed. The meditative traits that the participants identified were (1) awareness of body sensations and emotions; (2) disidentification from emotions and thoughts; (3) acceptance of situations, oneself, and others; and (4) compassion and loving kindness for oneself and others. The relational effects of these traits were (1) less reactivity in relationships; (2) greater freedom and safety in relationships; and (3) a new understanding of the nature of connection between people, marked by unity, separation, intimacy and independence. Implications for further research and for clinical practice are proposed.     

Proverb interpretation changes in aging

Recent investigations have emphasized the involvement of fronto-subcortical networks to proverb comprehension. Although the prefrontal cortex is thought to be affected by normal aging, relatively little work has been carried out to investigate potential effects of aging on proverb comprehension. In the present investigation participants in three age groups were assessed on a proverb comprehension task and a range of executive function tasks. The older group showed impairment in selecting correct interpretations from alternatives. They also showed executive function deficits, as reflected by reduced working memory and deficient set shifting and inhibition abilities. The findings of the present investigation showed proverb comprehension deficits in normal aging which appeared to be related to reduced executive skills.     

Processing of the Müller-Lyer illusion by a Grey parrot (Psittacus erithacus)

Alex, a Grey parrot (Psittacus erithacus) who identifies the bigger or smaller of two objects by reporting its color or matter using a vocal English label and who states "none" if they do not differ in size, was presented with two-dimensional Müller-Lyer figures (Brentano form) in which the central lines were of contrasting colors. His responses to "What color bigger/ smaller?" demonstrated that he saw the standard length illusion in the Müller-Lyer figures in 32 of 50 tests where human observers would also see the illusion and reported the reverse direction only twice. He did not report the illusion when (a) arrows on the shafts were perpendicular to the shafts or closely approached perpendicularity, (b) shafts were 6 times thicker than the arrows, or (c) after being tested with multiple exposures conditions that also lessen or eliminate the illusion for human observers. These data suggest that parrot and human visual systems process the Müller-Lyer figure in analogous ways despite a 175-fold difference in the respective sizes of their brain volumes. The similarity in results also indicates that parrots with vocal abilities like Alex's can be reliably tested on visual illusions with paradigms similar to those used on human subjects.     

A comparison of backward and forward spatial spans

The standard Corsi blocks task is frequently used to measure the capacity of visuospatial working memory, but the implications of the use of both forward and backward recall are still unclear. In the present study, we showed that the backward Corsi task is particularly powerful in discriminating between low- and high-spatial-ability individuals and involves different processes from those involved in the forward task. From a sample of 425 participants we selected one group of 20 high-spatial-ability participants and one of 20 low-spatial-ability participants. The results demonstrated that a backward spatial span offers specific information not available from a forward spatial span, and that there was no facilitation due to a descending format. In particular, in the low-spatial-ability group, performance was generally poorer, but backward Corsi recall was lower than forward recall, and participants did not show any advantage following the descending presentation format—which in some contexts is considered to reduce proactive interference. We conclude that the backward Corsi task has specific value and that the assumption of fully parallel verbal and visuospatial working-memory systems can lead to a variety of misunderstandings.     

"But you don't look Puerto Rican": the moderating effect of ethnic identity on the relation between skin color and self-esteem among Puerto Rican women

This exploratory study investigated whether ethnic identity, as assessed by Phinney's (1992) Multigroup Ethnic Identity Measure, functioned as a moderator in the relation between skin color (as measured by masked interviewer evaluation, participant self-report, and skin reflectance data) and self-esteem (as measured by Rosenberg's 1989 Self-Esteem Scale). In a sample of 53 English-speaking Puerto Rican women, a hierarchical multiple regression indicated that among lighter skinned women, those who felt less attached to their culture had less self-esteem than those who were more culturally embedded. Similarly, among darker skinned women, greater attachment to Puerto Rican culture was associated with greater self-esteem than a less defined ethnic identity. Findings are discussed in light of the beneficial effects of ethnic identity.     

Memory outcome after pediatric epilepsy surgery: objective and subjective perspectives.

Memory was investigated in 27 children and adolescents in a longitudinal study before and at one and two years after epilepsy surgery. A comparison group with intractable epilepsy (n = 15), matched in age, sex, age of seizure onset, and IQ, was studied at comparable points in time. Methods included administration of standardized measures of story recall and face recognition, and qualitative interviews to probe the participants' perceptions of their memory function over time. There was no significant change over time in either group on the standardized measures. Site and laterality of excision, age at surgery, and seizure outcome were not predictive of change within the surgical group. The narratives revealed facets of memory that were problematic in daily life. The objective and subjective results showed low concordance regarding change, possibly due to limitations in the objective measures for capturing semantic and autobiographical memory.     

Face processing at birth: a Thatcher illusion study

The present study was aimed at exploring newborns’ ability to recognize configural changes within real face images by testing newborns’ sensitivity to the Thatcher illusion. Using the habituation procedure, newborns’ ability to discriminate between an unaltered face image and the same face with the eyes and the mouth 180° rotated (i.e. thatcherized) was investigated. Newborns were able to discriminate an unaltered from the thatcherized version of the same face when stimuli were presented in the canonical upright orientation (Experiment 1), but failed to discriminate the same stimuli when they were presented upside‐down (Experiment 2). The results indicate that sensitivity to fine spatial information (defined as second‐order relational information) in processing upright faces is already present at birth.
