On the reinforcing value of helping behavior in a positive mood

In two separate experiments, each utilizing 33 male high school students, it was found that (a) after offering help, subjects reported that they were in a more positive mood than subjects who were not given the opportunity to help and (b) the proportion of helpers among subjects who expected their positive mood to continue was smaller than among those who did not share such an expectation. These findings are discussed in terms of the Negative State Relief model describing the relationship between mood and helping behavior.The authors wish to thank Dr. S. Dover for his valuable assistance during the early stages of the research.     

Windows into nothingness: terror management, meaninglessness, and negative reactions to modern art

Why do people dislike art that they find meaningless? According to terror management theory, maintaining a basic meaningful view of reality is a key prerequisite for managing concerns about mortality. Therefore, mortality salience should decrease liking for apparently meaningless art, particularly among those predisposed to unambiguous knowledge. Accordingly, mortality salience diminished affection for modern art in Study 1, and this effect was shown in Study 2 to be specific to individuals with a high personal need for structure (PNS). In Studies 3 and 4, mortality salient high-PNS participants disliked modern art unless it was imbued with meaning, either by means of a title or a personal frame of reference induction. Discussion focused on the roles of meaninglessness, PNS, and art in terror management.     

Suicide and attempted suicide: their relation to subjective social stress indicators

We investigated the relationship between the subjective perception of external stress and suicidal behavior, using a stress model which indicated that the probability of suicide and attempted suicide, as a reaction to stress, increases when social support systems fail or malfunction. We conceived the subjective perception of social stress as expressions of worry or dissatisfaction regarding cardinal life domains such as economic, security, or political situations. We defined support systems in terms of national solidarity expressed as positive (or improved) attitudes regarding the relations between various segments of the population, and we derived the data regarding the subjective indicators from continuing surveys of representative samples of urban Israeli population during the years 1967 through 1979. Eight stress indicators and three solidarity indicators were included, and our findings generally supported the theoretical model. However, the findings regarding men conformed best in relation to suicide, whereas those regarding women confirmed the theoretical model mainly in relation to attempted suicide. Contrary to the model, female suicide rates decreased in times of stress. Feelings of social solidarity in the population were found to reduce suicidal behavior of both men and women.     

Do explicit memory manipulations affect the memory blocking effect?

The memory blocking effect (MBE) occurs when people are prevented from completing word fragments because they studied orthographically similar words. Across 3 experiments, we investigated how manipulations that influence explicit memory tasks would influence the MBE. Although a significant MBE was observed in all 3 experiments, manipulating depth of processing (Experiment 1), time to complete the fragments (Experiment 2), and awareness of the MBE (Experiment 3) did not change the magnitude of the MBE. We discuss these results in the context of a suppression mechanism involved in retrieval-induced forgetting.     

Eliminating the memory blocking effect

Six experiments investigated the memory blocking effect (MBE) in which exposure to orthographically similar words (e.g., BALLOON) impairs one's ability to complete a similar fragment (e.g., BAL_ON_, solution is BALCONY). Experiments 1 and 2 demonstrated that blocking is not observed after a 72-hour delay; however, repetition priming was observed after the same delay. Experiments 3 and 4 showed that presenting unrelated semantic information during the fragment completion test eliminates blocking. Experiment 5 demonstrated that the MBE persists despite directed-forgetting instructions, and Experiments 5 and 6 demonstrated that activating both the solutions and blocking words for a particular fragment at study eliminates blocking. Collectively, the data demonstrate that reading orthographically similar primes automatically triggers retrieval of the blocking word and an executive control process works to manage this interference. A working framework that describes how an executive control mechanism could govern memory retrieval in the memory-blocking paradigm is presented to stimulate development of more advanced theoretical models that can explain blocking.     

Death Goes to the Polls: A Meta‐Analysis of Mortality Salience Effects on Political Attitudes

Terror management theory posits that people are motivated to affirm cultural meaning systems, including political ideologies, to avoid the awareness of mortality. Accordingly, studies show that increasing mortality salience (MS) intensifies people's attitudes toward political issues and figures. However, whereas in some studies MS increases affirmation of preexisting political ideologies, be they liberal or conservative (supporting a “worldview‐defense hypothesis”), in other studies MS elicits a general shift toward conservatism, regardless of preexisting ideology (supporting a “conservative‐shift hypothesis”). The current study used meta‐analysis to assess the overall magnitude of MS effects on explicitly political attitudes and to clarify the nature of these effects by comparing effect sizes for these competing hypotheses. The overall effect of MS on political attitudes was large (r = .50). The effects of MS‐induced worldview defense (r = .35) and conservative shifting (r = .22) were significant and statistically equivalent. We discuss the conditions (e.g., contextual salience of political values) under which conservative shifting or worldview defense occurs.
