Initial judgment task and delay of the final validity-rating task moderate the truth effect

Repeatedly seen or heard statements are typically judged to be more valid than statements one has never encountered before. This phenomenon has been referred to as the truth effect. We conducted two experiments to assess the plasticity of the truth effect under different contextual conditions. Surprisingly, we did not find a truth effect in the typical judgment design when using a ten minutes interval between statement repetitions. However, we replicated the truth effect when changing the judgment task at initial statement exposure or when using an interval of one week rather than ten minutes. Because none of the current truth effect theories can fully account for these context effects, we conclude that the cognitive processes underlying truth judgments are more complex than has hitherto been assumed. To close the theoretical gap, we propose a revised fluency attribution hypothesis as a possible explanation of our findings.     

The informative value of type of repetition: Perceptual and conceptual fluency influences on judgments of truth

We contrast the effects of conceptual and perceptual fluency resulting from repetition in the truth effect. In Experiment 1, participants judged either verbatim or paraphrased repetitions, which reduce perceptual similarity to original statements. Judgments were made either immediately after the first exposure to the statements or after one week. Illusions of truth emerged for both types of repetition, with delay reducing both effects. In Experiment 2, participants judged verbatim and paraphrased repetitions with either the same or a contradictory meaning of original statements. In immediate judgments, illusions of truth emerged for repetitions with the same meaning and illusions of falseness for contradictory repetitions. In the delayed session, the illusion of falseness disappeared for contradictory statements. Results are discussed in terms of the contributions of recollection of stimulus details and of perceptual and conceptual fluency to illusions of truth at different time intervals and judgmental context conditions.     

Reading is believing: the truth effect and source credibility

Five experiments explored how source reliability influences people’s tendency to rate statements as more credible when they were encountered earlier (the truth effect). Undergraduates read statements from one reliable source and one unreliable source. Statements read multiple times were perceived as more valid and were more often correctly identified on a general knowledge test than statements read once or not at all. This occurred at varying retention intervals whether the statements originated from a reliable or unreliable source, when people had little memory for the statements themselves or their source, and when the discrediting information about the sources came either before or after reading the facts. While repetition aided recognition and source accuracy, both were unaffected by the reliability of the source. Consistent with the source monitoring framework, familiarity may create an illusion of truth for statements when people lack source-specifying cues, especially cues regarding the reliability of the source.     

Fluency and positivity as possible causes of the truth effect

Statements’ rated truth increases when people encounter them repeatedly. Processing fluency is a central variable to explain this truth effect. However, people experience processing fluency positively, and these positive experiences might cause the truth effect. Three studies investigated positivity and fluency influences on the truth effect. Study 1 found correlations between elicited positive feelings and rated truth. Study 2 replicated the repetition-based truth effect, but positivity did not influence the effect. Study 3 conveyed positive and negative correlations between positivity and truth in a learning phase. We again replicated the truth effect, but positivity only influenced judgments for easy statements in the learning phase. Thus, across three studies, we found positivity effects on rated truth, but not on the repetition-based truth effect: We conclude that positivity does not explain the standard truth effect, but the role of positive experiences for truth judgments deserves further investigation.     

A processing fluency-account of funniness: Running gags and spoiling punchlines

Earlier theories on humour assume that funniness stems from the incongruity resolution of the surprising punchline and thus an insight into the joke's meaning. Applying recent psychological theorising that insight itself draws on processing fluency being the ease and speed with which mental content is processed, it is predicted that increasing the fluency of processing the punchline of a joke increases funniness. In Experiments 1 and 2, significant nouns from the punchlines or from the beginnings of jokes were presented before a joke was rated in funniness. Pre-exposing punchline words 15 minutes and even only 1 minute before the eventual joke led to increased funniness ratings. In contrast, pre-exposing punchline words directly before a joke led to decreased funniness ratings. Furthermore, pre-exposing the beginning of a joke 1 minute before the joke had no effects on funniness. Experiment 3 ruled out exposure-facilitated punchline anticipation as alternative mechanism, and Experiment 4 replicated this fluency effect with typing font as manipulation. These findings also show that pre-exposing a punchline, which in common knowledge should spoil a joke, can actually increase funniness under certain conditions.     

Between conflict and reconciliation: the hard truth

In the context of the fairly recent Truth and Reconciliation Commissions (TRC), I examine phenomenologically the nature of truth as the essential condition for overcoming social and political conflicts, and as an instrument for enforcing so-called “transitional justice” periods and promoting reconciliation. I also briefly approach the limits of this truth’s possibility of being recognized, if its evaluative and practical dimensions and its appeal to an “intelligence of emotions” do not prevail over its merely theoretical claims. Though not expounding Schutz’s and Husserl’s contributions, and meditating on phenomena they did not deal with, I carry out this reflection inspired by their work and methodological approach. The case study used as an intuitive illustration is the recent Peruvian Truth and Reconciliation Commission.

Effects of context on the rate of conjunctive responses in the probabilistic truth table task

The probabilistic truth table task involves assessing the probability of "If A then C" conditional sentences. Previous studies have shown that a majority of participants assess this probability as the conditional probability P(C│A) while a substantial minority responds with the probability of the conjunction A and C. In an experiment involving 96 participants, we investigated the impact on the rate of conjunctive responses of the context in which the task is framed. We show that a context intended to lead participants to consider all the possible cases (i.e. the throw of a die known to allow six possibilities) elicited more conjunctive responses than a context assumed not to have this effect (an unfamiliar deck of cards). These results suggest that the step of inferring the probability can distort our assessment of participants' interpretation of conditional sentences. This might compromise the validity of the probabilistic task in studying conditional reasoning.     

Context reinstatement and memory for intrinsic versus extrinsic context: The role of item generation at encoding or retrieval

According to many theoretical accounts, reinstating study context at the time of test creates optimal circumstances for item retrieval. The role of context reinstatement was tested in reference to context memory in several experiments. On the encoding phase, participants were presented with words printed in two different font colors (intrinsic context) or two different sides of the computer screen (extrinsic context). At test, the context was reinstated or changed and participants were asked to recognize words and recollect their study context. Moreover, a read‐generate manipulation was introduced at encoding and retrieval, which was intended to influence the relative salience of item and context information. The results showed that context reinstatement had no effect on memory for extrinsic context but affected memory for intrinsic context when the item was generated at encoding and read at test. These results supported the hypothesis that context information is reconstructed at retrieval only when context was poorly encoded at study.     

Categorical priming of famous person recognition: a hitherto overlooked methodological factor can resolve a long-standing debate

The Burton, Bruce and Johnston [Burton, A. M., Bruce, V., & Johnston, R. A. (1990). Understanding face recognition with an interactive activation model. British Journal of Psychology, 81, 361-380] model of person recognition proposes that representations of known persons are connected by shared semantic attributes. This predicts that priming should be observed between persons from the same category, e.g. famous persons with the same occupation. Empirical investigations to date have produced mixed results, and comparison of methods suggests that priming based on shared occupation may have been suppressed by the presence of prime-target pairs representing a stronger relationship of close association. In the present experiment, 72 participants performed a familiarity decision to famous names preceded by close associates or members of the same occupational category. As predicted, categorical priming was observed in the group of participants for whom the same occupation prime-target pairs were presented before the close-associate pairs, but not in the group for whom the two types of relationship were intermixed. Associate priming was significant in both groups. These results are attributed to differing levels of processing of the primes, invoked by participants' observation of the most salient prime-target relationship.

Information presentation format moderates the unconscious-thought effect: The role of recollection

The unconscious-thought effect occurs when distraction improves complex decision-making. In two experiments using the unconscious-thought paradigm, we investigated the effect of presentation format of decision information (i) on memory for decision-relevant information and (ii) on the quality of decisions made after distraction, conscious deliberation or immediately. We used the process-dissociation procedure to measure recollection and familiarity. The two studies showed that presenting information blocked per criterion led participants to recollect more decision-relevant details compared to a presentation by option. Moreover, a Bayesian meta-analysis of the two studies provided strong evidence that conscious deliberation resulted in better decisions when the information was presented blocked per criterion and substantial evidence that distraction improved decision quality when the information was presented blocked per option. Finally, Study 2 revealed that the recollection of decision-relevant details mediated the effect of presentation format on decision quality in the deliberation condition. This suggests that recollection contributes to conscious deliberation efficacy.     

Spirituality moderates the effect of stress on emotional and physical adjustment

This study examined the relationship of spirituality with emotional and physical adjustment to daily stress. One hundred and thirteen college students completed questionnaire measures of spirituality, daily stress, affect, and physical symptoms at two times one month apart. The results showed that spirituality buffered the adverse effect of stress on adjustment, controlling for the use of various coping strategies. The findings have implications for developing prevention programs to improve people's coping skills by incorporating greater emphasis on spirituality.     

Recognising what you like: Examining the relation between the mere-exposure effect and recognition

The perceptual fluency/attributional model of the mere-exposure effect proposed by R. F. Bornstein and P. D'Agostino (1992) predicts that when recognition of a previously presented stimulus is above chance, feelings of fluency associated with that stimulus are discounted and thus the amount of fluency (mis)attributed to liking is reduced. This correction process results in smaller mere-exposure effects for supraliminal stimuli than for “subliminal” stimuli because when recognition is below chance participants are unaware of the source of fluency and they do not engage in correction. We tested this prediction in three experiments by presenting photographs of faces (Experiments 1 and 2) and polygons (Experiment 3) at varying exposure frequencies for 40 ms and 400 ms durations. Contrary to the prediction of the model, a significant mere-exposure effect was only found when recognition performance was at its highest level. Furthermore, across the three experiments liking and recognition were positively correlated.

Effects of simple- and complex-place contexts in the multiple-context paradigm

In four experiments, a total of 384 undergraduates incidentally learned a list of 24 nouns twice in the same context (same-context repetition) or different contexts (different-context repetition). Free recall was measured in a neutral context. Experiments 1, 2, and 3 used a context repetition (same- or different-context repetition) × inter-study and retention intervals (10 min or 1 day) between-participants design. Context was manipulated by the combination of place, social environment, and encoding task (Experiment 1), place and social environment (Experiment 2), or place alone (Experiment 3). Experiment 4 used a context repetition × type of context (context manipulated by place or by place, social environment, and encoding task) between-participants design, with a 10-min inter-study interval and a one-day retention interval. The present results indicate that the determinant of the superiority of same- or different-context repetition in recall is the type of context. Implications of the results were discussed.     

Stimulus type and the list strength paradigm

In recognition memory, increasing the strength of studied items does not reduce performance on other items, an effect dubbed the null list strength effect (LSE). While this finding has been replicated many times, it has rarely been tested using stimuli other than single words. Kinnell and Dennis (2012 Kinnell, A., & Dennis, S. (2012). The role of stimulus type in list length effects in recognition memory. Memory & Cognition, 40, 311–325. doi: 10.3758/s13421-011-0164-2[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) recently tested for the presence of list length effects using non-word stimulus classes while controlling for the confounds that are present in list length designs. Small list length effects were found for fractal and face images. We adopted the same paradigm and stimuli used by Kinnell and Dennis to test whether these stimuli would be susceptible to list strength effects as well. We found significant LSEs for fractal images, but null LSEs for face images and natural scene photographs. Stimuli other than words do appear to be susceptible to list strength effects, but these effects are small and restricted to particular stimulus classes, as is the case in list length designs. Models of memory may be able to address differences between these stimulus classes by attributing differences in representational overlap between the stimulus classes.

Repetition and Spacing Effects on True and False Recognition in the DRM Paradigm

Dubuisson, J.-B., Fiori, N. & Nicolas, S. (2012) Repetition and spacing effects on true and false recognition in the DRM paradigm. Scandinavian Journal of Psychology 53, 382-389. With the Deese-Roediger-McDermott (DRM) paradigm, the repetition effect on false memory had never been clarified. More importantly, the spacing effect on false memory was never directly investigated. So, we carried out two experiments to examine these effects on true and false recognition. In experiment 1, participants studied DRM lists which were presented one, three or five times. In experiment 2, we manipulated the repetition mode (massed vs. spaced with a short interval or a long interval) to explore the spacing effect. The results showed that true recognition increased monotonically with list repetition (experiment 1) and repetition spacing (experiment 2). The most striking finding was a similar spacing effect but no repetition effect on false recognition. Thus, these results were principally discussed in the light of the activation-monitoring framework.     

Close Encounters With the Midwest: Forming Identity in a Bicultural Context

This study uses semi-structured interviews to examine how 16 people of Latvian heritage negotiated their cultural identities in high school (retrospectively) and at midlife (concurrently). Participants' high school and midlife cultural identity patterns were coded as marginalized, separated, assimilated, alternating integrated, or blended integrated. Although eleven participants were found to have had marginalized, separated, or alternating integrated patterns in high school, all 16 had either assimilated or blended integrated patterns at midlife. Further, there is evidence that the contexts in which identity negotiation occurred—specifically, the rigidity of the participants' Latvian and American contexts in high school and their relative openness at midlife—influenced these changes in pattern. The findings also underscore the importance of taking into account within-group differences when studying how people negotiate their cultural identities.
