The Impact of Beliefs Concerning Deception on Perceptions of Nonverbal Behavior: Implications for Neuro-Linguistic Programming-Based Lie Detection. Flavia Spiroiu. Journal of Police and Criminal Psychology, https://link.springer.com/article/10.1007/s11896-018-9278-9

Abstract: Regularly employed in a forensic context, the Neuro-Linguistic Programming (NLP) model purports that the behavioral distinction between somebody who is remembering information and somebody who is constructing information lies in the direction of their eye movements. This strategy reflects numerous current approaches to lie detection, which presume that nonverbal behavior influences perceptions and judgments about deception. The present study emphasized a reverse order by investigating whether beliefs that an individual is deceptive influence perceptions of the respective individual’s nonverbal behavior as indicated by observed eye movement patterns. Sixty participants were randomly assigned to either a group informed that right eye movements indicate constructed and thus deceptive information or a group informed that left eye movements indicate constructed and thus deceptive information. Each participant viewed six investigative interviews depicting the eye movement patterns of mock suspects labeled as deceptive or truthful. The interviews were structured according to different right/left eye movement ratios. Results revealed that participants reportedly observed the deceptive suspects displaying significantly more eye movements in the direction allegedly indicative of deception than did the truthful suspects. This result occurred despite the fact that the actual eye movement ratios in both deceptive/truthful sets of interviews were identical and the eye movements were predominantly in the opposite direction of that allegedly indicative of deception. The results are discussed in the context of encoding-based cognitive-processing theories. Limitations on the generality of the results are emphasized and the applicability (or lack thereof) of NLP-based lie detection in forensic contexts is discussed.

Crush on You: Romantic Crushes Increase Consumers’ Preferences for Strong Sensory Stimuli

Crush on You: Romantic Crushes Increase Consumers’ Preferences for Strong Sensory Stimuli. Xun (Irene) Huang, Ping Dong, Meng Zhang. Journal of Consumer Research, ucy053, https://doi.org/10.1093/jcr/ucy053

Abstract: What influences consumers’ preferences for strong versus weak sensory stimuli? In this paper, we find converging evidence that when the experience of a romantic crush is salient, consumers have an enhanced preference for options that elicit strong sensory stimulation (e.g., loud music, strongly flavored food). We demonstrate this effect across seven studies using a broad array of products and services as stimuli. We further show that these consumers have a heightened motivation to achieve greater sensations from the desired person, but cannot act in a way that directly satisfies this motivation, leading them to be more likely to turn to products and services for the desired sensations. Moreover, we find that the effect is specific to the experience of a romantic crush and cannot be generalized to other interpersonal experiences (e.g., passionate love, stable romantic relationship, unmet sexual desire).

Pavlov's Reflex before Pavlov: Early Accounts from the English, French and German Classic Literature

Pavlov's Reflex before Pavlov: Early Accounts from the English, French and German Classic Literature. S Jarius S, B Wildemann. European Neurology, 2017;77:322-326. https://doi.org/10.1159/000475811

Abstract: The concept of classical conditioning (CC), strongly connected with the name and work of the Russian physiologist Ivan Petrovich Pavlov (1849-1936), has become the foundation of the modern science of learning and, in particular, of the influential theories of Watson and Skinner and the entire school of behaviourism. In this paper, we give a number of forgotten accounts of CC in the English, French, and German classic literature that pre-date Pavlov's reports by decades or even centuries. These instances are taken from works of the 16th, 18th, and 19th centuries - authored by some of the finest writers of England (Sterne, Locke), France (Rabelais), and Germany (Jean Paul) - and indicate that the psychological mechanisms now described as CC were known long before Pavlov and his successors elaborated on them in a systematic way.

False memory production in one experimental paradigm won't predict susceptibility to false memories in other paradigms

Patihis, L., Frenda, S. J., & Loftus, E. F. (2018). False memory tasks do not reliably predict other false memories. Psychology of Consciousness: Theory, Research, and Practice, 5(2), 140-160. http://dx.doi.org/10.1037/cns0000147

Abstract: Several laboratory techniques have been developed over the last few decades that reliably produce memory distortions. However, it is unclear whether false memory production in one experimental paradigm will predict susceptibility to false memories in other paradigms. In Experiment 1, 202 undergraduates participated in a misinformation experiment and semiautobiographical tasks involving three measures of memory distortion (suggestion, imagination, emotion). We established high internal consistency in individual differences measures and statistically significant experimental effects where we would expect them (e.g., the misinformation effect). However, false memory production in one task did not predict false memories in other paradigms. In Experiment 2, 163 adults participated in a misinformation experiment, a false memory word list task (Deese–Roediger–McDermott), and semiautobiographical false news story tasks. Again we found no consistent predictive relationships among various false memories. In both studies, no individual differences predicted memory distortion susceptibility consistently across tasks and across experiments. At this time, false memory production in a given laboratory task does not appear to adequately predict false memories in other tasks, a finding with implications for using these tasks to predict memory distortion in real world situations.

Flynn effect and its reversal are both environmentally caused

Flynn effect and its reversal are both environmentally caused. Bernt Bratsberg and Ole Rogeberg. Proceedings of the National Academy of Sciences, June 11, 2018. 201718793. https://doi.org/10.1073/pnas.1718793115

Significance: Using administrative register data with information on family relationships and cognitive ability for three decades of Norwegian male birth cohorts, we show that the increase, turning point, and decline of the Flynn effect can be recovered from within-family variation in intelligence scores. This establishes that the large changes in average cohort intelligence reflect environmental factors and not changing composition of parents, which in turn rules out several prominent hypotheses for retrograde Flynn effects.

Abstract: Population intelligence quotients increased throughout the 20th century—a phenomenon known as the Flynn effect—although recent years have seen a slowdown or reversal of this trend in several countries. To distinguish between the large set of proposed explanations, we categorize hypothesized causal factors by whether they accommodate the existence of within-family Flynn effects. Using administrative register data and cognitive ability scores from military conscription data covering three decades of Norwegian birth cohorts (1962–1991), we show that the observed Flynn effect, its turning point, and subsequent decline can all be fully recovered from within-family variation. The analysis controls for all factors shared by siblings and finds no evidence for prominent causal hypotheses of the decline implicating genes and environmental factors that vary between, but not within, families.

Men are more supportive of Islamic veiling than women, but women with more sons are more supportive of veiling and more likely to wear veils than women with fewer sons; men were more religious if they had more sons

Who suppresses female sexuality? An examination of support for Islamic veiling in a secular Muslim democracy as a function of sex and offspring sex. Khandis R. Blake, Maleke Fourati, Robert C. Brooks. Evolution and Human Behavior, https://doi.org/10.1016/j.evolhumbehav.2018.06.006

Abstract: Whether it is men or women who suppress female sexuality has important implications for understanding gendered relations, ultimately providing insight into one widespread cause of female disadvantage. The question of which sex suppresses female sexuality more avidly, however, neglects that our interests are never ambiguously masculine or feminine; each of us has a combination of male and female kin which alters how much of our future fitness derive from each sex. Here we exploit a nationally representative sample of 600 Tunisians to test whether support for Islamic veiling—a proxy for female sexual suppression—is more common amongst one sex than the other, and is affected by the relative sex of one's offspring (i.e., the number of sons relative to daughters). We find that men are more supportive of Islamic veiling than women, but women with more sons are more supportive of veiling and more likely to wear veils than women with fewer sons. All effects were robust to the inclusion of religiosity, which was weaker amongst men and unrelated to the number of sons a woman had. The number of daughters affected neither religiosity nor support for veiling, but did increase women's likelihood of wearing contemporary, fashionable Tunisian veils compared with no head covering. We further found that men were more religious if they had more sons. Overall, these findings highlight that far from being the fixed strategy of one sex or the other, female sexual suppression manifests facultatively to promote one's reproductive interests directly or indirectly by creating conditions beneficial to one's descendent kin. These results show that both men and women can suppress female sexuality, although the function in either case appears more closely aligned with male rather than female interests.

Religious disbelief was related to cognitive flexibility; lower frequency of religious service attendance was related to cognitive flexibility; religious affiliation and engagement may shape & be shaped by cognitive control styles towards flexibility versus persistence

Cognitive flexibility and religious disbelief. Leor Zmigrod et al. Psychological Research, https://link.springer.com/article/10.1007/s00426-018-1034-3

Abstract: Cognitive flexibility is operationalized in the neuropsychological literature as the ability to shift between modes of thinking and adapt to novel or changing environments. Religious belief systems consist of strict rules and rituals that offer adherents certainty, consistency, and stability. Consequently, we hypothesized that religious adherence and practice of repetitive religious rituals may be related to the persistence versus flexibility of one’s cognition. The present study investigated the extent to which tendencies towards cognitive flexibility versus persistence are related to three facets of religious life: religious affiliation, religious practice, and religious upbringing. In a large sample (N = 744), we found that religious disbelief was related to cognitive flexibility across three independent behavioural measures: the Wisconsin Card Sorting Test, Remote Associates Test, and Alternative Uses Test. Furthermore, lower frequency of religious service attendance was related to cognitive flexibility. When analysing participants’ religious upbringing in relation to their current religious affiliation, it was manifest that current affiliation was more influential than religious upbringing in all the measured facets of cognitive flexibility. The findings indicate that religious affiliation and engagement may shape and be shaped by cognitive control styles towards flexibility versus persistence, highlighting the tight links between flexibility of thought and religious ideologies.

The core cognitive architecture responsible for cumulative culture and technological progress also supports the propagation of rituals: our socially motivated propensity for engaging in high‐fidelity imitation

The Social Glue of Cumulative Culture and Ritual Behavior. Mark Nielsen. Child Development Perspectives, https://doi.org/10.1111/cdep.12297

Abstract: Cumulative culture, where innovations are incorporated progressively into a population's stock of skills and knowledge, generating more sophisticated repertoires, is a core aspect of human cognition underpinning the technological advances that characterize our species. Cumulative culture relies on our proclivity for high‐fidelity imitation, a characteristic that emerged phylogenetically early in our evolutionary history and emerges ontogenetically early in our development. Commensurate with this proclivity to copy others comes a tradeoff that behaviors that are functionally irrelevant will be easily maintained and transmitted. Rituals are an expression of this. In this article, I argue that the core cognitive architecture responsible for cumulative culture and technological progress also supports the propagation of rituals: our socially motivated propensity for engaging in high‐fidelity imitation.
