Congruence of personality and life events in depression

Consistent with the personality-event congruence hypothesis, highly sociotropic depressed patients (n = 19) reported more recent negative interpersonal events than negative autonomy events and more negative interpersonal events than did highly autonomous depressed patients (n = 22), for whom the hypothesis was not supported. There was no evidence of such congruence among nondepressed schizophrenic patients (n = 44). In a second study, there was significant personality-event congruence in dysphoric students (n = 26) but not in nondysphoric students (n = 56). Both the high-sociotropy and high-autonomy dysphoric groups separately yielded nonsignificant trends consistent with congruence. These findings add to the growing support for the importance of the sociotropy construct in depression and weaker support for the autonomy construct or its measurement, and they suggest that the congruence effect does not generalize to all psychopathologies.     

The two faces of alcohol myopia: attentional mediation of psychological stress

Two studies provided evidence that alcohol's relationship to psychological stress is indirect and is mediated by the allocation of attention. Study 1 found that, as the attentional demands of a distracting activity increased, so did alcohol's reduction of anxiety. Study 2 replicated this effect and found that a highly demanding activity could reduce anxiety even without alcohol. This study further implicated the role of attention in anxiety reduction by demonstrating a relationship between changes in anxiety and response latency to a secondary monitoring task. Finally, in both experiments, intoxicated subjects who did not perform any activity showed an increase in anxiety. From these data, we argue that alcohol affects psychological stress, to an important degree, through its ability, in conjunction with ongoing activity, to affect the amount of attention paid to stressful thoughts.     

Peer-group association and adolescent tobacco use

Mosbach & Leventhal (1988) examined the relation of cigarette smoking to peer-group identification in rural Wisconsin adolescents. They found that among dirts (problem-prone youth), regulars (average youth), hot-shots (good social or academic performers), and jocks (athletes), youth most likely to smoke were dirts and hot-shots. We performed a replication with a Southern California cohort and also for use of smokeless tobacco. We hypothesized that jocks would be the main users of smokeless tobacco. We identified the same groups and an additional one, skaters (skateboarders or surfers). As Mosbach & Leventhal found, cigarettes were used most by dirts. Contrary to their results, but consistent with other research, we found that hot-shots were least likely to smoke. Contrary to our prediction, we found that skaters and dirts were more likely to use smokeless tobacco than were jocks. Our data show that both tobacco forms are used by problem-prone youth.     

Endorsement of dysfunctional beliefs depends on current mood state

In two studies we tested the hypothesis that endorsement of dysfunctional beliefs depends on current mood state for persons who are vulnerable to depression. The first study showed that reports of dysfunctional beliefs vary with spontaneous diurnal mood fluctuations in 47 depressed psychiatric patients. The effect of mood state was highly significant (p less than .01); dysfunctional thinking increased when mood was worst and decreased when mood was best. The second study conceptually replicated this finding in a population of asymptomatic subjects. As predicted, reports of dysfunctional beliefs varied as a function of mood state in 14 persons who had experienced a depressive episode but not in 27 who had never been depressed. These findings support the cognitive theory of depression, which proposes that dysfunctional beliefs are vulnerability factors for depression but also that reporting of dysfunctional beliefs depends on current mood state.     

Selective processing of threat cues in posttraumatic stress disorder

Vietnam combat veterans with (n = 15) and without (n = 15) posttraumatic stress disorder (PTSD) performed a modified Stroop task in which they named the colors of neutral words (e.g., INPUT), positive words (e.g., LOVE), obsessive-compulsive disorder (OCD) words (e.g., GERMS), and PTSD words (e.g., BODYBAGS). In contrast to normal controls, PTSD patients took significantly longer to color-name PTSD words than to color-name neutral, OCD, and positive words. Because Stroop interference reflects involuntary semantic activation, it may provide a quantitative measure of intrusive cognitive activity--the hallmark symptom of PTSD.     

CROSS-CULTURAL COMPARISONS ON PSYCHOSEMANTICS OF ICONS AND GRAPHICS

This study is to report a cross-cultural comparison on perceptions of icons and graphics and their relationships. Data were ratings of 10 icons and 10 graphics against 21 bipolar semantic differential scales from 325 college students in three countries, Mexico, Columbia, and Japan. Cross-cultural factor analyses resulted in the identification of four semantic (three affective and one denotative) features, three icon factors, and three graphic factors. Indigenous cultural means of these iconic and graphic factors were computed and used to probe cross-cultural similarities and differences in perceptions. Psychosemantics of icon factors were further predicted by graphic factors through canonical correlation. This study concludes the importance of implicit cultural meanings of nonverbal figures in intercultural communications. The implications of this study are also discussed.     

Reasons for Living Following Success and Failure in Suicidal and Nonsuicidal College Students1

To see if suicide ideators responded differently than nonideators after success or failure experiences, 61 college students who were relatively high or low ideators participated in a computer task on which half got bogus success feedback, the other half got bogus failure feedback. Both groups then completed the Reasons for Living Inventory (RFL). Two (High versus Low Suicide) X 2 (Success or Failure) analyses indicated main effects for suicide on overall RFL and four of the six RFL subscales. Although there were no main effects for success versus failure, an interaction indicated that, in the failure condition, low suicidal subjects were significantly higher than high suicidal subjects in overall reasons for living. Results suggest that suicidal individuals may be vulnerable to failure, and may need interventions to help them avoid potential failure or to bolster their coping mechanisms.     

The rule learning behavior of reading disabled and normal children as a function of task characteristics and instruction

The purpose of this research was to investigate rule learning in reading disabled (RD) and normal children (chronological age and reading age (RA) match) when required to (a) abstract rules independently, and (b) use rules after instruction. Study 1 required the children to solve problems using shapes and letters. Although there was no difference between groups in the rate of problem solving when children were asked to abstract rules independently, the pattern of errors was different. The RD children made a greater proportion of errors on the negative instance for the more complex problems. In particular, this occurred on the letter task which involved psycholinguistic categorization. After instruction, the RA controls made more errors than the other groups. Study 2 was an analogous pseudoword reading task. Even with statistical adjustment for differences in prior grapheme-phoneme (g-p) rule knowledge, the RD children performed less accurately than the RA controls when they had to abstract rules, although this was restricted to the most difficult rule (rule of e). There was no difference after instruction in rule application, although the pattern of errors and post-test results indicated that the RD children continued to experience decoding difficulty. These results suggest a phonologically based productive deficit which interferes with the learning of g-p rules. This may be part of a more general language deficit which includes psycholinguistic categorization. Despite the severity of this handicap, RD children seem responsive to instruction.     

Degree of cognitive impairment and the dissociation of implicit and explicit memory

One group of normal elderly adults and two groups of cognitively impaired elderly adults were compared on an implicit and an explicit memory task. Degree of impairment affected explicit memory; the mildly and moderately impaired elderly adults demonstrated significantly reduced recognition performance. Degree of impairment also affected implicit memory priming performance, particularly for low frequency items, as measured by a word completion task. Explicit memory performance declined for both cognitively impaired groups, but implicit memory performance was sensitive to the degree or severity of impairment, causing a decline in performance only in the moderately impaired group.     

The influence of experimenter attitude on the performance of children of different cognitive ability levels

We investigated the influence of the experimenter's attitude on children's performance in a classification task. We chose 96 children (M age: 5 years, 9 months) on the basis of their performance in a spontaneous classification task. Forty-eight children made partial alignments on the basis of a link established from one object to the next (O-level group); 48 looked for objects having one common property (P-level group). The children had to perform a dichotomy task in two testing situations: one with a caring experimenter, and one with an indifferent experimenter. In the O-level group, the children's performance was superior when the experimenter was caring even though they did not seem to notice the difference between the two attitudes. P-level children clearly distinguished the experimenter attitudes, but their performance remained the same. To determine children's actual abilities accurately, researchers must take into account children's interactions with both objects and partners.
