Poor performance on cognitive tasks in depression: Doing too much or not enough?

Depressed people perform poorly on cognitive tasks. It is unclear whether these deficits are due to decreased devotion of task-related resources or to increased attention to non-task-related information. In the present study, we examined the degree to which depressed and healthy adults displayed pupillary motility that varied at the frequency of presented stimuli on a cognitive task, which we interpreted as task-related processing, and at other frequencies, which we interpreted as reflecting intrinsic processing. Depressed participants made more consecutive errors than did controls. More pupillary motility at other frequencies was associated with poorer performance, whereas more pupillary motility at the frequency of presented stimuli was associated with better performance. Depressed participants had more pupillary motility at other frequencies, which partially mediated observed deficits in cognitive performance. These findings support the hypothesis that allocating cognitive resources to intrinsic processing contributes to observed cognitive deficits in depression.     

A mouse with a roof? effects of phonological neighbors on processing of words in sentences in a non-native language

The architecture of the language processing system for speakers of more than one language remains an intriguing topic of research. A common finding is that speakers of multiple languages are slower at responding to language stimuli in their non-native language (L2) than monolingual speakers. This may simply reflect participants' unfamiliarity with words in the L2, however it may also be the reflection of interference from competing lexical alternatives both across and within the participants' multiple languages. In the current studies (one behavioral, one electrophysiological) we investigate how interference from phonologically similar words within the L2 alone may account for problems in auditory language comprehension in non-native speakers. To this end a cross modal lexical priming (CMLP) paradigm was implemented, which allowed us to look for effects of spoken word primes embedded in sentences on the recognition of target stimuli. Specifically, we investigated whether a word such as mouse, which has a close phonological neighbor, house, would show a modulating effect on recognition of a word semantically related to house but not to mouse (i.e., roof). We hypothesized that L2 speakers, less efficient at categorizing phonemes in their L2 would show a difference in the processing of roof preceded by mouse as compared to roof preceded by another unrelated word, such as lamp, due to a residual co-activation of the phonological neighbor mouse. Furthermore, L1 speakers, highly proficient at recognizing phonemes in their native tongue, should show no such effect. The results of both studies clearly support our hypothesis, indicating that phonological neighbors in the L2 may greatly interfere with L2 word recognition.     

The reading ability of good and poor temporal processors among a group of college students

In this study, we examined whether good auditory and good visual temporal processors were better than their poor counterparts on certain reading measures. Various visual and auditory temporal tasks were administered to 105 undergraduates. They read some phonologically regular pseudowords and irregular words that were presented sequentially in the same ("word" condition) and in different ("line" condition) locations. Results indicated that auditory temporal acuity was more relevant to reading, whereas visual temporal acuity was more relevant to spelling. Good auditory temporal processors did not have the advantage in processing pseudowords, even though pseudoword reading correlated significantly with auditory temporal processing. These results suggested that some higher cognitive or phonological processes mediated the relationship between auditory temporal processing and pseudoword reading. Good visual temporal processors did not have the advantage in processing irregular words. They also did not process the line condition more accurately than the word condition. The discrepancy might be attributed to the use of normal adults and the unnatural reading situation that did not fully capture the function of the visual temporal processes. The distributions of auditory and visual temporal processing abilities were co-occurring to some degree, but they maintained considerable independence. There was also a lack of a relationship between the type and severity of reading deficits and the type and number of temporal deficits.     

The contribution of rapid visual and auditory processing to the reading of irregular words and pseudowords presented singly and in contiguity

This study examined the relative involvement of rapid auditory and visual temporal resolution mechanisms in the reading of phonologically regular pseudowords and English irregular words presented both in isolation and in contiguity as a series of six words. Seventy-nine undergraduates participated in a range of reading, visual temporal, and auditory temporal tasks. The correlation analyses suggested a general timing mechanism across modalities. There were more significant correlations between the visual temporal measures and irregular word reading and between the auditory measures and pseudoword reading. Auditory gap detection predicted pseudoword reading accuracies. The low temporal frequency flicker contrast sensitivity measure predicted the accuracies of isolated irregular words and pseudowords presented in contiguity. However, when a combined speed-accuracy score was used, visible persistence at both low and high spatial frequencies and auditory gap detection were active in the reading of pseudowords presented in contiguity. Sensory processing skills in both visual and auditory modalities accounted for some of the variance in the reading performance of normal undergraduates, not just reading-impaired students.     

Orangutan leaf-carrying for nest-building: Toward unraveling cultural processes

We report an empirical study on leaf-carrying, a newly discovered nest-building technique that involves collecting nest materials before reaching the nest site. We assessed whether leaf-carrying by rehabilitant orangutans on Kaja Island, Central Kalimantan, owes to cultural influences. Findings derive from ca 600 h observational data on nesting skills and nesting associations in Kaja’s 42 resident rehabilitants, which yielded 355 nests and 125 leaf-carrying cases by 34 rehabilitants. Regional contrasts with 14 other communities (7 rehabilitant, 7 wild) indicated cultural influences on leaf-carrying on Kaja. Association data showed exceptional social learning opportunities for leaf-carrying on Kaja, with residents taking differential advantage of these opportunities as a function of development, experience, and social position. Juvenile males with basic nesting skills were most influenced by social input. Most (27) leaf-carriers had probably learned leaf-carrying when caged and 7 probably learned it on Kaja. Social priming was probably the main impetus to leaf-carrying on Kaja, by simply prompting observers to copy when leaf-carrying associates collected nesting materials, what they collected, and where they used their collected materials. Implications concern acquisition processes and ontogenetic schedules that orchestrate sets of features—needs or interests, cognitive abilities, social preferences—which enable cultural transmission.     

Gender Characteristics and Relationship Adjustment: Another Look at Similarity-Complementarity Hypotheses

ABSTRACT The present study examined how the similarity and complementarity of gender-related attitudes, behaviors, interests, and personality traits related to partner selection and relationship adjustment in the context of serious, romantic relationships. Results revealed the important role of gender-related attitudes in relationships, indicating that study participants tended to be paired with partners who held similar attitudes, and that couples who were similar in attitudes had higher dyadic adjustment. Furthermore, the nature of the couples' attitudes affected (a) the extent to which couples were paired on the basis of complementary interests and behaviors, and (b) the relation between partner's gender-related behaviors and dyadic adjustment. Results support previous research citing the importance of attitude similarity in interpersonal attraction, and demonstrate that these findings can be generalized to ongoing, close relationships.     

The family origins of empathic concern: a 26-year longitudinal study

This study examined whether adult empathic concern was associated with parent behavior in early childhood. Subjects were drawn from a longitudinal sample first investigated by Sears, Maccoby, and Levin (1957). At age 31, 75 subjects completed the Adjective Checklist (Gough & Heilbrun, 1965, 1983), from which an index of empathic concern was derived. Scores on this index were regressed on 11 parenting dimensions derived from maternal interviews when the subjects were 5 years old. The results revealed a significant multiple R indicating that, taken together, the parenting dimensions predicted the level of empathic concern at age 31. Adult levels of empathic concern were most strongly related to the following parenting dimensions: paternal involvement in child care, maternal tolerance of dependent behavior, maternal inhibition of child's aggression, and maternal satisfaction with the role of mother.     

Setting limits on children's behavior: The differential effects of controlling vs. informational styles on intrinsic motivation and creativity

The imposition of external constraints on an activity has frequently been shown to undermine intrinsic motivation. Given that limits must often be set upon peoples' activities, especially in parenting and education, the present study addressed the question of whether limits can be set without undermining intrinsic motivation for the activity being limited. Using cognitive evaluation theory, contrasting limit setting styles of either a controlling or informational nature, or no limits, were placed upon forty-four first- and second-grade children engaged in a painting activity. The intrinsic motivation, enjoyment, creativity, and quality of artistic production were expected to be decreased by controlling limits relative to informational and no-limits, which were not expected to differ from each other. The results provided substantial support for these predictions, suggesting that limits can be set without undermining intrinsic motivation if they are informational in nature. Support was also found for the consensual assessment of creativity method recently developed by Amabile (1982a). Results of the study are discussed along with the general relation between creativity and intrinsic motivation.     

Indirectly expressed motivational deficits among arthritic adults

The present experiment examined whether adults suffering from arthritis evidence motivational deficits reflective of a diminished sense of effectiveness in dealing with their environment. Content-coding of imaginative stories revealed that both osteoarthritics and rheumatoid arthritics possess significantly lower levels of achievement and power motivation compared with control subjects. Furthermore, arthritic patients with poor health status, as assessed by the Arthritis Impact Measurement Scales, were found to be especially low in their level of achievement motivation. No differences between arthritics and healthy controls were found when self-report measures of achievement and power motivation were used in place of the thematically coded indices. That is, arthritics reported that their desire to do something better and their desire to influence others was just as strong as that of healthy adults. This suggests that arthritic adults suffer from a motivational deficit that may not be revealed in response to direct questions about their motives or goals.This research was funded by a National Institute of Health Grant (AR 20613) to the Multipurpose Arthritis Center at Boston University and by a fellowship from the Seaver Institute.     

Related attributes in the choice of comparison others: It's there,but it isn't all there is

Subjects within a group of nine were supposedly given different amounts of practice prior to taking a test on which performance was either related or unrelated to practice. After taking the test, each subject was given his score, his rank order in the group, and the amount of practice presumably done by each of the other group members. The subject was then given a choice of which performance score he would like to know; a second choice was also given. On both first and second choices, subjects in the related condition were more likely to choose to see the scores of others with the same amount of practice. Related condition subjects were more interested in their comparison choices and thought they had done better on the task than unrelated subjects. In addition to this confirmation of the related attributes hypothesis, there was a significant tendency toward comparison on the basis of similarity of performance per se and a significant tendency toward upward comparison.
