Situation models and retrieval interference: pictures and words

Previous studies have found that interference in long-term memory retrieval occurs when information cannot be integrated into a single situation model, but this interference is greatly reduced or absent when the information can be so integrated. The current study looked at the influence of presentation format-sentences or pictures-on this observed pattern. When sentences were used at memorisation and recognition, a spatial organisation was observed. In contrast, when pictures were used, a different pattern of results was observed. Specifically, there was an overall speed-up in response times, and consistent evidence of interference. Possible explanations for this difference were examined in a third experiment using pictures during learning, but sentences during recognition. The results from Experiment 3 were consistent with the organisation of information into situation models in long-term memory, even from pictures. This suggests that people do create situation models when learning pictures, but their recognition memory may be oriented around more "verbatim", surface-form memories of the pictures.     

Fan effects in event-based prospective memory

Three experiments investigated whether event-based prospective memory was affected by the associative fan of the cues to be detected. The associative fan was operationally defined as the number of associates paired with event-based cues in a paired associate learning phase. Subsequent to the paired associate learning, participants were given a lexical decision task in which event-based cues were embedded. The results from Experiments 1 and 2 confirmed that a larger associative fan significantly reduced event-based cue detection. The third experiment confirmed that the absolute strength of an association does not affect performance, rather the number of associations does. As an ancillary issue, the authors tested whether cue detection was affected by the familiarity of the background words used in the lexical decision task. No consistent evidence for a discrepancy plus search model of prospective memory was found.     

When you and I are "we," you are not threatening: the role of self-expansion in social comparison

Many theories of self-evaluation emphasize the power of social comparison. Simply put, an individual is thought to gain esteem whenever she or he outperforms others and to lose esteem when he or she is outperformed. The current research explored interdependent self-construal as a moderator of these effects. Two studies used a priming task to manipulate the level of self-construal and investigate effects of social comparison in dyadic (Study 1) and group situations (Study 2). Both studies demonstrated that when the target for comparison is construed as part of the self, his or her successes become cause for celebration rather than costs to esteem. Additionally, gender differences in chronic relational and collective self-construals moderated the patterns of social comparison in a form similar to that of priming relational and collective self-construals.     

Situation models,propositions, and the fan effect

According to theories of language comprehension, people can construct multiple levels of representation: the surface form, the propositional text base, and the situation model. In this study, I looked at how the referential nature of memory probes affects the experience of retrieval interference. All the subjects memorized sentences about objects in locations (e.g., “The potted palm is in the hotel”). When memory probes were sentences and, therefore, referential and most closely associated with the situation model level, no interference was observed during retrieval for information that could be integrated into a common situation model. In contrast, interference was observed in such cases when the memory probes were concept pairs (POTTED PALM-HOTEL) and hence not directly referential. This is interpreted to mean that nonreferential memory probes involve surface form and text base representations more than do referential sentence probes.     

An observation on the role of context variability in free recall

The authors conducted 3 experiments investigating the effect of context variability and word frequency on free recall. Context variability refers to the number of pre-experimental contexts in which a given word is experienced. Both between-subjects and within-subjects manipulations of context variability demonstrated a distinct advantage for low context variability words. Standard word frequency effects were obtained in 2 of the 3 experiments, but the common finding of no word frequency differences in mixed lists of high and low word frequency may depend on the level (low vs. high) of context variability. The authors speculate that the advantage for low context variability items may accrue from better item-to-list context associations or better storage of contextual information as a consequence of the smaller pre-experimental contextual fan that these items possess.     

How I see me depends on how I see we: the role of attachment style in social comparison

The self-concept is a social, flexible construct that shifts in response to the salience of a relationship partner. Three related experiments found that the tendency to pursue closeness in relationships (as measured by attachment style) served as a moderator of the shift. Specifically, individuals who avoid closeness in relationships became less similar to salient friends via contrast effects, whereas those who pursued closeness in relationships became more similar to salient friends via assimilation effects. Results are discussed in terms of their implications for the nature of the self-concept and the importance of friendships.     

Preservation of implicit memory in adult children of alcoholics

The authors investigated implicit memory in 21 adult children of alcoholics (ACAs) and 24 control individuals (all college undergraduates) who performed a serial reaction time task (SRT) to evaluate their implicit memory performance and their formation of new associations. Each group was presented with 5 blocks of 100 trials per block in which Blocks 1-4 contained a 10-item repeating sequence; Block 5 was a pseudo-random sequence. The latency difference between Block 4 and Block 5 presumably measure implicit memory. The amount of implicit memory did not differ (in ms) between the ACAs (M = 55 ms) and the controls (M = 67 ms). Implicit memory (at least as measured by the SRT task) appears to be preserved in ACAs.     

When a compliance without pressure strategy fails due to a minority dissenter: A case of “behavioral conversion”

While a strategy of compliance without pressure (Joule, 1987) had the effect of inducing almost all of a group of smoking subjects to stop smoking first for 18 hours then for 3 days, simply observing someone (an accomplice) break his or her own initial agreement to abstain from smoking for 18 hours was enough to bring about a substantial reduction in the willingness of other subjects to later abstain for 3 days. However, subjects did not follow the lead of the accomplice immediately, and persisted in their agreement to abstain for 18 hours. This pattern of indirect, but not direct influence, suggests that there may be a type of minority influence at work here that represents a sort of behavioral conversion.     

Sex differences in dealing with bureaucracy

The present study set out to test the popular stereotype of male communicative dominance in the context of dealing with bureaucracy. The study examined the responses of male and female officials of various bureaucratic organizations to different persuasive appeals activated by male and female clients. Log-linear analysis was used to reveal the relationships between sex composition of client-official dyads and outcome across types of organizations and types of persuasive appeal. Findings indicate that the sex of the client and the official significantly affected the outcome only when the type of appeal was taken into account. Although male and female clients did not differ in rates of successful outcome, males were more persuasive when using stronger (i.e., normative) appeals, and females were more effective when applying weaker (i.e., altruistic) appeals. The results demonstrate that no simple answer can be found to the old issue of sex-bound persuasiveness. The answer is highly dependent on a combination of contextual aspects, communicative tactics, and measures of response.This research was supported by the Research Authority of the University of Haifa.
