The influence of partial‐match cues on event‐based prospective memory

In event‐based prospective memory tasks people form an intention to respond when an environmental cue signals that conditions are appropriate to fulfil an intended activity. In the ongoing activity the authors embedded partial‐match cues that only partially, but not completely, satisfied the conditions required to make a prospective response. The consequence of encountering these partial‐match cues was to increase responses to appropriate prospective memory cues encountered later. This outcome occurred both with semantic and orthographic cues, but only the former led to longer processing latencies of the partial‐match cues. This asymmetry suggests that partial‐match cues may not need to be processed consciously in order to benefit event‐based prospective memory. A parametric manipulation of the number of partial‐match cues resulted in numerically but not statistically better prospective memory. Consequently, partial‐match cues may function as overt reminders of the intention to respond or they may serve to engage participants in self‐initiated remindings of the intention.     

Working memory capacity predicts listwise directed forgetting in adults and children

Flashbulb memories are highly vivid and long-lasting memories for events that are emotionally significant and personally important. Research in this area typically focuses on negative events such as the assassination of John F. Kennedy, the events of 11 September 2001, and the start of Operation Desert Storm. However, the current study examines flashbulb memory formation to the positive event of receiving an invitation to join a university-wide social organisation (Greek Life). Results suggest that this is an event capable of producing vivid flashbulb memories with high ratings of belief in accuracy and high consistency over time.     

Self-regulatory efficacy's role in the relationship between exercise identity and perceptions of and actual exercise behaviour

Identity theory posits that when people endorse an identity they maintain or alter their behaviour in order to behave consistently with that identity. This assertion is supported in the exercise context where strength of exercise identity relates to exercise behaviour. Less is known about self-regulatory constructs that may aid individuals in behaving consistently with their exercise identity. Self-regulatory efficacy may mediate the relationship between exercise identity and exercise given the influence of this variable on exercise self-regulation; this relationship has not been examined. Exercise identity research has focused on the relationship between identity and behaviour; yet, identity theory recognizes perceptions of identity-behaviour consistency as theoretically important. Through influencing how identity-relevant information is processed, self-regulatory efficacy may also mediate the relationship between exercise identity and perceptions of identity-behaviour consistency.ObjectiveIdentity and social cognitive theories were used to examine self-regulatory efficacy as a mediator between exercise identity and i) exercise behaviour and ii) perceptions of identity-behaviour consistency.Method/designUndergraduate students (n = 311) were followed for 8 weeks. At baseline, participants completed demographic, exercise identity and exercise measures. After 4 weeks they reported their self-regulatory efficacy and after 8 weeks they reported their perceptions of identity-behaviour consistency and their exercise behaviour.ResultsConsistent with theory, self-efficacy mediated the relationship between exercise identity and both outcomes.ConclusionsFindings extend the exercise identity literature by providing empirical support for self-regulatory efficacy as a mechanism through which exercise identity strength leads to exercise behaviour and the perception of behavioural consistency with exercise identity meanings.     

Dissonance-induced false memories: Evidence from a free-choice paradigm

People often misremember the past as consistent with the present. Recent research using an induced-compliance paradigm has revealed that cognitive dissonance is one mechanism that can underlie this memory distortion. We sought to replicate and extend this finding using a free-choice paradigm: Participants made either an easy or a difficult choice between two smartphones and, either immediately or two days later, reported their memories for their decision experience. Participants who made a difficult decision produced the spread-of-alternatives effect expected by dissonance theory, and they were also more likely than those in the easy conditions to misremember their initial decision more favourably than they had initially rated it. Overall, our findings replicate the effect of dissonance on memory distortion and, further, show that the effect generalises to other dissonance-inducing situations.     

Coloured Letters and Numbers (CLaN): A reliable factor-analysis based synaesthesia questionnaire

Synaesthesia is a heterogeneous phenomenon, even when considering one particular sub-type. The purpose of this study was to design a reliable and valid questionnaire for grapheme-colour synaesthesia that captures this heterogeneity. By the means of a large sample of 628 synaesthetes and a factor analysis, we created the Coloured Letters and Numbers (CLaN) questionnaire with 16 items loading on 4 different factors (i.e., localisation, automaticity/attention, deliberate use, and longitudinal changes). These factors were externally validated with tests which are widely used in the field of synaesthesia research. The questionnaire showed good test–retest reliability and construct validity (i.e., internally and externally). Our findings are discussed in the light of current theories and new ideas in synaesthesia research. More generally, the questionnaire is a useful tool which can be widely used in synaesthesia research to reveal the influence of individual differences on various performance measures and will be useful in generating new hypotheses.     

A re-examination of the algebraic properties of the AHP as a ratio-scaling technique

The Analytic Hierarchy Process (AHP) ratio-scaling approach is re-examined in view of the recent developments in mathematical psychology based on the so-called separable representations. The study highlights the distortions in the estimates based on the maximum eigenvalue method used in the AHP distinguishing the contributions due to random noises from the effects due to the nonlinearity of the subjective weighting function of separable representations. The analysis is based on the second order expansion of the Perron eigenvector and Perron eigenvalue in reciprocally symmetric matrices with perturbations. The asymptotic distributions of the Perron eigenvector and Perron eigenvalue are derived and related to the eigenvalue-based index of cardinal consistency used in the AHP. The results show the limits of using the latter index as a rule to assess the quality of the estimates of a ratio scale. The AHP method to estimate the ratio scales is compared with the classical ratio magnitude approach used in psychophysics.     

Ambivalence, discomfort, and motivated information processing

In two studies we examined the nature and consequence of ambivalent attitudes. In the first study, we assessed whether holding ambivalent attitudes was aversive, and tested whether this aversion was resolved through biased information processing. To do this we manipulated participants’ attributions of the discomfort associated with an ambivalent message through a pill manipulation (tense vs. relaxed). Participants who attributed their discomfort to their ambivalence reported more negative emotions and generated more one-sided thoughts than participants who attributed their discomfort to the pill. In the second study, we examined the conditions necessary for ambivalence reduction. Results suggest that people spontaneously engage in biased information processing in order to resolve their ambivalence.     

Individual arousal-related performance zones effect on temporal and behavioral patterns in golf routines

AimConsistency, both in duration and behavior, of pre-performance routines has been closely related to overall performance quality. However, recent findings highlight that psychological and physiological states may have important implications for routine consistency. To further clarify this relationship, the present study sought to examine changes in routine consistency with respect to optimal and non-optimal arousal states.MethodThe present case study observed the performance routines of three high-skilled golfers during three rounds of competitive golf. Measures of arousal (heart rate) and outcome performance were used to determine each golfer’s Individual Arousal-related Performance Zones (IAPZs) (Kamata, Hanin, & Tenenbaum, 2002). Subsequently, temporal and behavioral patterns (consistency and number of rehearsal swings and glances toward the target) for both the full swing and golf putt were assessed across poor, moderate, and optimal levels of the golfer’s IAPZ.ResultsIdiosyncratic differences in routine patterns, both behaviorally and temporally were evident. More importantly, the consistency of the routines for each golfer varied under different arousal-related performance zones. That is, the temporal and behavioral patterns of the golfers varied in idiosyncratic ways across the IAPZ levels.ConclusionsThese findings suggest that factors that influence a performer’s arousal level can lead to idiosyncratic variations in a performer’s routine. Observation of these routine changes can provide insight into the negative tendencies that an athlete can have when performing outside their optimal zone. With this knowledge, practitioners can be more effective in helping athletes monitor and regulate arousal, which will ultimately lead to enhanced performance.     

Cultural influences on preference consistency: Consistency at the individual and collective levels

Previous research has shown that there are cultural differences in self-concept consistency across situations. However, little is known about cultural differences in preference consistency over time. The present research examined whether Americans are more consistent in their preferences over time than are Japanese. As hypothesized, there were cultural differences in self-reported ( and ) and actual ( and ) preference consistency over time. Further, cultural differences in preference consistency at the individual level (Study 1) were found to aggregate into collective level differences ( and ) in the consistency of preference trends, such as the popularity of baby names. Implications and future directions are discussed.
