Is Lying Bound to Commitment? Empirically Investigating Deceptive Presuppositions,Implicatures, and Actions

Lying is an important moral phenomenon that most people are affected by on a daily basis—be it in personal relationships, in political debates, or in the form of fake news. Nevertheless, surprisingly little is known about what actually constitutes a lie. According to the traditional definition of lying, a person lies if they explicitly express something they believe to be false. Consequently, it is often assumed that people cannot lie by more indirectly communicating believed-false claims, for instance by merely conversationally implicating them. In this paper, we subject this claim to an empirical test. In a preregistered study of 300 participants, we investigate how people judge cases of implicit deceptions that would usually be excluded by the traditional definition of lying (i.e., conversational implicatures, presuppositions, and nonverbal actions). Our results show that people do in fact consider it possible to lie by indirect means, suggesting that people have a broader concept of lying than is usually assumed. Moreover, our findings indicate that lie judgments are closely tied to the extent to which agents are perceived as having committed themselves to the believed-false claims they have communicated. We discuss the implications of our results for the traditional definition of lying and propose a new commitment-based definition of lying that can account for the findings of our experiment.     

Cultural differences in distraction processing: influence of context at retrieval

Cultural differences in information processing affect perceptual judgment, attention, and memory. We investigated whether cultural differences in processing patterns, specifically East Asian participants’ tendency to encode holistically, compared to Western tendencies to process analytically, affect performance on an implicit memory test. First, participants completed a 1-back task on pictures with superimposed distracting words. After a delay filled with a computerised Corsi block task, they performed a word fragment task in which some fragments could be completed with the distracting words from the 1-back task. Critically, fragments were presented with the same pictures as previously seen (matched condition), with no pictures (control condition), or with pictures from other trials on the 1-back task (mismatched condition). Non-Asian Canadian participants showed virtually no priming for distraction, independent of the reinstatement of encoding context. East Asian Canadian participants showed superior priming for fragments that had been paired with their original pictures. They did not show evidence of a detriment for the mismatched, relative to control, condition.     

Contrast class cues and performance facilitation in a hypothesis-testing task: evidence for an iterative counterfactual model

Hypothesis-testing performance on Wason’s (Quarterly Journal of Experimental Psychology 12:129–140, 1960) 2–4–6 task is typically poor, with only around 20% of participants announcing the to-be-discovered “ascending numbers” rule on their first attempt. Enhanced solution rates can, however, readily be observed with dual-goal (DG) task variants requiring the discovery of two complementary rules, one labeled “DAX” (the standard “ascending numbers” rule) and the other labeled “MED” (“any other number triples”). Two DG experiments are reported in which we manipulated the usefulness of a presented MED exemplar, where usefulness denotes cues that can establish a helpful “contrast class” that can stand in opposition to the presented 2–4–6 DAX exemplar. The usefulness of MED exemplars had a striking facilitatory effect on DAX rule discovery, which supports the importance of contrast-class information in hypothesis testing. A third experiment ruled out the possibility that the useful MED triple seeded the correct rule from the outset and obviated any need for hypothesis testing. We propose that an extension of Oaksford and Chater’s (European Journal of Cognitive Psychology 6:149–169, 1994) iterative counterfactual model can neatly capture the mechanisms by which DG facilitation arises.     

Autonomy and defensiveness: experimentally increasing adaptive responses to health-risk information via priming and self-affirmation

Health information is often ineffective in motivating health-behaviour change. One way to improve information effectiveness might be to highlight autonomy, which is associated with less defensiveness and more adaptive psychological functioning. Three studies assessed whether experimentally elevating autonomy led to adaptive responses to risk information about alcohol consumption. In Study 1 (N?=?104), participants completed either an autonomy prime or a neutral prime task and read either risk information about the dangers of alcohol consumption or neutral information. Among high-risk participants in the autonomy prime condition, those who read risk information reported greater autonomous motivation towards moderate alcohol consumption than did those in the neutral information condition. Study 2 (N?=?157) compared two types of autonomy prime tasks with a neutral condition. For high-risk participants who read risk information, the autonomy prime tasks elicited greater autonomous motivation, more positive attitudes and greater intentions to drink in moderation than did the neutral prime task. Study 3 (N?=?130) found that for high-risk participants who read risk information, autonomy prime participants reported less subsequent alcohol consumption than did neutral prime participants. The results are discussed in terms of the benefits of autonomy for adaptive responses to risk information.     

The convergent and concurrent validity of trait-based prototype assessment of personality disorder categories in homeless persons

The DSM-5 proposal indicates that personality disorders (PDs) be defined as collections of maladaptive traits but does not provide a specific diagnostic method. However, researchers have previously suggested that PD constructs can be assessed by comparing individuals' trait profiles with those prototypic of PDs and evidence from the five-factor model (FFM) suggests that these prototype matching scores converge moderately with traditional PD instruments. The current study investigates the convergence of FFM PD prototypes with interview-assigned PD diagnoses in a sample of 99 homeless individuals. This sample had very high rates of PDs, which extends previous research on samples with more modest prevalence rates. Results indicated that diagnostic agreement between these methods was generally low but consistent with the agreement previously observed between explicit PD measures. Furthermore, trait-based and diagnostic interview scores evinced similar relationships with clinically important indicators such as abuse history and past suicide attempts. These findings demonstrate the validity of prototype methods and suggest their consideration for assessing trait-defined PD types within DSM-5.     

Genius [corrected] without the "Great Man": new possibilities for the historian of psychology

The Carlylian style of history, more commonly known as the "Great Man" approach, presented the "genius" as an individual worthy of celebration: history as hero worship. This style, which characterized the first wave of the history of psychology, has gone out of historiographic fashion. In its place is the "new history," which is marked by its external focus and privileging of social factors and cultural context in its explanations. This shift in historiographic sensibilities has also led to a revision in the appropriate subject matter for psychologist-historians. This article argues, in contrast, that it is possible to study eminent individuals without resorting to hagiography, and it presents various methods that could be used for this purpose. The aim of such an endeavor is to create a space for critically and historically informed perspectives on greatness and to suggest a reconsideration of the value of an "historical psychology".     

Psychophysiological and subjective indices of emotion as a function of age and gender

Old, middle-aged and young persons of both genders were presented with slides containing pictorial stimuli that varied in emotional content. Each picture was rated on three dimensions: (1) valence; (2) arousal; and (3) dominance, using a 25-point scale. Heart rate, skin conductance, and forehead and cheek EMG were recorded during each slide presentation. The old and middle-aged groups showed greatly attenuated psychophysiological responses, compared to the young group. However, the old and middle-aged subjects used more extreme ratings than the young subjects on both the valence and arousal dimensions. Females were more valence-sensitive than males, but males in general used more extreme ratings of arousal than females. These results suggest a tendency to report increased felt emotion but decreased physiological response to emotional stimuli across the life span.     

Subliminal priming of autobiographical memories

The current research examined subliminal priming of autobiographical memories. In Experiment 1 the subliminal primes consisted of affect-associated words (positive vs negative) and were presented just before the participants retrieved specific experiences to cue-words. The subliminal primes produced an inhibitory effect on autobiographical memory retrieval, with significantly lower positive ratings given to the emotional content of experiences retrieved after positive primes than given to experiences retrieved after negative primes. The subliminal primes for the second experiment consisted of words that related to specific lifetime periods (early childhood vs late childhood/early adulthood). A negative priming effect resulted again, with earlier life experiences retrieved after the presentation of late childhood/early adulthood primes. We believe the negative priming effects obtained in both experiments are consistent with predictions based on the self-memory system model of autobiographical memory. The results of this research may also explain mood-incongruent recall.     

Increased susceptibility to proactive interference in adults with dyslexia?

Recent findings show that people with dyslexia have an impairment in serial-order memory. Based on these findings, the present study aimed to test the hypothesis that people with dyslexia have difficulties dealing with proactive interference (PI) in recognition memory. A group of 25 adults with dyslexia and a group of matched controls were subjected to a 2-back recognition task, which required participants to indicate whether an item (mis)matched the item that had been presented 2 trials before. PI was elicited using lure trials in which the item matched the item in the 3-back position instead of the targeted 2-back position. Our results demonstrate that the introduction of lure trials affected 2-back recognition performance more severely in the dyslexic group than in the control group, suggesting greater difficulty in resisting PI in dyslexia.     

The Relationship of Target and Response Complexity in Coincident Timing Performance

This paper reports two experiments concerned with the interaction of response and target factors in a coincident timing situation. Coincident timing involves executing a response to intercept a moving target. The target response relationship was manipulated in the first experiment by providing some targets with no structure (linear path) and others containing 1 and 2 bounce points. In the second experiment, responses required 0, 1, or 2 reversals in direction. The results provide tentative support for the notion that structure in the target path could be linked to the key temporal response dynamics for improved performance consistency, and that subjects may alter their response structure to incorporate this linkage. This can be further extended to the advantage of simply moving while perceiving movement. This paper stresses the importance of examining the perceptual and motor requirements of the coincident timing skill in unison.
