Is the child ‘father of the Man’? Evaluating the stability of genetic influences across development

This selective review considers findings in genetic research that have shed light on how genes operate across development. We will address the question of whether the child is ‘father of the Man’ from a genetic perspective. In other words, do the same genetic influences affect the same traits across development? Using a ‘taster menu’ approach and prioritizing newer findings on cognitive and behavioral traits, examples from the following genetic disciplines will be discussed: (a) developmental quantitative genetics (such as longitudinal twin studies), (b) neurodevelopmental genetic syndromes with known genetic causes (such as Williams syndrome), (c) developmental candidate gene studies (such as those that link infant and adult populations), (d) developmental genome‐wide association studies (GWAS), and (e) DNA resequencing. Evidence presented here suggests that there is considerable genetic stability of cognitive and behavioral traits across development, but there is also evidence for genetic change. Quantitative genetic studies have a long history of assessing genetic continuity and change across development. It is now time for the newer, more technology‐enabled fields such as GWAS and DNA resequencing also to take on board the dynamic nature of human behavior.     

A rapprochement between emotion and cognition: amygdala, emotion, and self-relevance in episodic-autobiographical memory

Lindquist et al. remark that not all fear instances lead to heightened amygdalar activity and, instead, point to roles of the amygdala in detecting "motivationally salient "or "emotionally impactful" stimuli. By reviewing research on the amygdala's functions in episodic-autobiographical memory, we further emphasize the involvement of the amygdala in coding the subjective relevance and extracting the biological and social significance of the stimuli.     

Children's scale errors with tools

Children sometimes make scale errors, attempting to interact with tiny object replicas as though they were full size. Here, we demonstrate that instrumental tools provide special insight into the origins of scale errors and, moreover, into the broader nature of children's purpose-guided reasoning and behavior with objects. In Study 1, 1.5- to 3.5-year-olds made frequent scale errors with tools in a free-play session. Study 2 utilized a novel forced-choice method, representing a stronger test by handing 2-year-olds a feasible alternative for goal achievement, but children continued to make scale errors. Study 3 confirmed that errors were not based in perceptual immaturity. Results are explained using a framework of teleofunctional (purpose-based) reasoning as a powerful and early developing influence on children's actions.     

Building and Handling Therapeutic Closeness in the Therapist-Client Relationship in Behavioral and Cognitive Psychotherapy

The present study unpacks an important dimension of clinical practice from the therapists’ vantage point. We interviewed 26 therapists in private practice about how the personal relationship with the client works from their perspective and conducted a grounded theory analysis. Three categories emerged. One refers to scope, aims and corollaries of the connection with the client; a second to preventing harm and managing drawbacks; and a third to taking therapeutic advantage of challenges related to closeness. Together, these categories form a model that describes how the close connection modifies therapeutic effects and generates challenges the therapist needs to deal with. The closer the dyad, the easier therapists will affect and be affected by the client. Therapists try to direct closeness to where it can nourish client process without harming the relationship, the client or themselves, and when closeness backfires, they may still try to harness uninvited effects for the benefit of therapy. This model concerning therapists’ lived experience is offered to inform research on the therapist-client relationship and as a contribution to clinical competency models.     

Infants’ sense of approximate numerosity: Heritability and link to other concurrent traits

The ability to perceive approximate numerosity is present in many animal species, and emerges early in human infants. Later in life, it is moderately heritable and associated with mathematical abilities, but the etiology of the Approximate Number System (ANS) and its degree of independence from other cognitive abilities in infancy is unknown. Here, we assessed the phenotypic specificity as well as the influence of genetic and environmental factors on the ANS in a sample of 5-month-old twins (N = 514). We found a small-to-moderate but statistically significant effect of genetic factors on ANS acuity (heritability = 0.18, 95% CI: 0.02, 0.33), but only when differences in numerosity were relatively large (1:4 ratio). Non-verbal ability assessed with the Mullen Scales of Early Learning (MSEL) was found to be heritable (0.47; 95% CI: 0.34, 0.57) and the phenotypic association between ANS acuity and non-verbal ability performance was close to zero. Similarly, we found no association between ANS acuity and general attention during the task. An unexpected weak but statistically significant negative association between ANS acuity and scores on the receptive language scale of the MSEL was found. These results suggest that early ANS function may be largely independent from other aspects of non-verbal development. Further, variability in ANS in infancy seems to, to some extent, reflect genotypic differences in the population.

Highlights

• Assessing 514 infant twins with eye tracking, we found that infants' sense of approximate numerosity is heritable and not positively associated with concurrent attentional, cognitive or motor abilities.
• These results have implications for our understanding of development of mathematical ability and the link between cognitive abilities early in postnatal life.

     

Psychological entitlement: interpersonal consequences and validation of a self-report measure

Nine studies were conducted with the goal of developing a self-report measure of psychological entitlement and assessing its interpersonal consequences. The Psychological Entitlement Scale (PES) was found to be reliable and valid (Study 1, 2), not associated with social desirability (Study 2), stable across time (Study 3), and correlated negatively with two of the Big Five factors: agreeableness and emotional stability (Study 4). The validity of the PES was confirmed in studies that assessed willingness to take candy designated for children (Study 5) and reported deservingness of pay in a hypothetical employment setting (Study 6). Finally, the PES was linked to important interpersonal consequences including competitive choices in a commons dilemma (Study 7), selfish approaches to romantic relationships (Study 8), and aggression following ego threat (Study 9). Psychological entitlement has a pervasive and largely unconstructive impact on social behavior.     

The correspondence between Erich Neumann and C.G. Jung on the occasion of the November pogroms, 1938

In the light of recently‐published correspondence between Jung and Neumann, this paper considers and connects two aspects of their relationship: Jung's theory of an ethno‐specific differentiation of the unconscious as formulated in 1934, and the relationship between Jung and Neumann at the beginning of the Holocaust in 1938–with Jung as the wise old man and a father figure on one hand, and Neumann as the apprentice and dependent son on the other. In examining these two issues, a detailed interpretation of four letters, two by Neumann and two by Jung, written in 1938 and 1939, is given. Neumann's reflections on the collective Jewish determination in the face of the November pogroms in 1938 led Jung to modify his view, with relativization and secularization of his former position. This shift precipitated a deep crisis with feelings of disorientation and desertion in Neumann; the paper discusses how a negative father complex was then constellated and imaged in a dream. After years of silence, the two men were able to renew the deep bonds that characterized their lifelong friendship.     

The Etiology of Behavior Problems in 7-Year-Old Twins: Substantial Genetic Influence and Negligible Shared Environmental Influence for Parent Ratings and Ratings by Same and Different Teachers

Parent ratings of behavior problems in childhood show substantial genetic influence and modest shared environmental influence. However, few studies have compared these results to teacher ratings and no previous studies have compared same-teacher ratings to different-teacher ratings. 3,714 7-year-old twin pairs in the Twins Early Development Study were rated by parents and teachers on the Strengths and Difficulties Questionnaire. Substantial heritability and negligible shared environmental influence were found for data from all three raters for total behavior problems, hyperactivity, prosocial behavior, peer problems, conduct problems, and emotional symptoms. Sex-limitation models revealed similar results for males and females, although there was some evidence for greater heritability for boys, especially when twins were rated by the same teacher.     

Auditory, visual, tactile, olfactory, and bodily hallucinations in patients with obsessive-compulsive disorder

Although much attention has been paid to patients who lack insight into their obsessional beliefs, less importance has been given to individuals with obsessive-compulsive disorder (OCD) who display perceptual disturbances typically found in psychotic disorders, including schizophrenia, schizoaffective disorders, or mood disorders with psychotic features. We would like to call the attention to a phenomenon that has been neglected in the psychiatric literature: the occurrence of hallucinations and related phenomena in patients with OCD. In this case report, we describe five clinical vignettes of patients with OCD with hallucinations in several different sensory modalities, including the auditory, the visual, the tactile, the olfactory, and the cenesthetic ones. Further psychopathological research should clarify the clinical significance of hallucinations among patients with OCD.
