Cognitive content-specificity in future expectancies: role of hopelessness and intolerance of uncertainty in depression and GAD symptoms

The present study examined cognitive content-specificity in future-event predictions associated with symptoms of depression and generalized anxiety disorder (GAD). College undergraduates (N=284) completed measures of depression, GAD, and rated their certainty that a given set of positive and negative outcomes were or were not likely to happen in their future. Participants also completed measures of hopelessness and intolerance of uncertainty (IU). Individuals (N=263) completed the same measures again 6 weeks later. Certainty in an absence of positive future outcomes was associated with symptoms of depression but not GAD, and hopelessness mediated this relationship - concurrently and when examining change scores over 6 weeks. Certainty in negative outcomes was concurrently associated with both symptoms of depression and GAD, and hopelessness partially mediated these relationships. IU predicted concurrent increases in depression and GAD symptoms, and negative-outcome certainty partially mediated the IU-depression but not the IU-GAD symptom relationship. Change in certainty did not mediate the relationship between changes in IU and GAD symptoms but partially mediated the relationship between change in IU and depression symptoms over time. Hopelessness appears to play a unique role in the relationship between reduced anticipation of positive future outcomes and depression. Although less clearly suggested by the data, IU may contribute to both depression and GAD symptoms but may do so through different pathways.     

Beyond sex differences: Family and occupational roles' impact on women's and men's dreams

The question addressed is: do recent changes in the occupational roles of women, with their indirect influence on men's lives, have an impact on the dreams of women and men? Three groups of parents (N=96) including in equal numbers, mothers at home, wage-earning mothers and fathers, kept a dream diary from which two dreams per dreamer were content analyzed. Assuming continuity between daytime and dream experiences, it was hypothesized that differences in manifest dream content would be a function of single versus dual role enactment, rather than sex. Contrary to predictions, statistical analyses performed on selected dream variables did not yield significant differences between groups for pleasant and unpleasant emotions, friendly interactions and aggression. Dream characters, and the concerns they reflect, were found to vary, though, according to social roles. Commitment to their family was reflected above all in the mothers' at home dreams, while commitment to their profession took precedence in those of the wage-earning mothers. Comparable commitment to work and family was found among the fathers. Findings suggest that as gender differences in waking life decrease, so may differences in dreams.     

Cues to speech segmentation: Evidence from juncture misperceptions and word spotting

The question of whether Dutch listeners rely on the rhythmic characteristics of their native language to segment speech was investigated in three experiments. In Experiment 1, listeners were induced to make missegmentations of continuous speech. The results showed that word boundaries were inserted before strong syllables and deleted before weak syllables. In Experiment 2, listeners were required to spot real CVC or CVCC words (C = consonant, V = vowel) embedded in bisyllabic nonsense strings. For CVCC words, fewer errors were made when the second syllable of the nonsense string was weak rather than strong, whereas for CVC words the effect was reversed. Experiment 3 ruled out an acoustic explanation for this effect. It is argued that these results are in line with an account in which both metrical segmentation and lexical competition play a role.     

Hedonic contrast and condensation: Good stimuli make mediocre stimuli less good and less different

Loud sounds make soft sounds softer (contrast) and also make them less discriminable (which we callcondensation). We report on parallel phenomena in hedonics: Good stimuli reduce the pleasantness of less good stimuli, and also reduce people’s preferences among the less good stimuli. In Experiment 1, subjects rated the pleasantness of fruit juices diluted to approximate hedonic neutrality. Subjects who had just previously drunk and rated some good-tasting full-strength juices rated the diluted juices lower than did subjects who had not (hedonic contrast). In Experiment 2, subjects drank pairs of diluted juices and rated their preference for one juice over the other. Subjects who had just previously drunk and rated pairs of full-strength juices gave lower preference ratings between the diluted juices than did subjects who had not (condensation). Thus the same stimulus set produced contrast in Experiment 1 and condensation in Experiment 2, paralleling results in loudness.
