Relating magnitudes: the brain's code for proportions

Whereas much is known about how we categorize and reason based on absolute quantity, data exploring ratios of quantities, as in proportions and fractions, are comparatively sparse. Until recently, it remained elusive whether these two representations of number are connected, how proportions are implemented by neurons and how language shapes this code. New data derived with complementary methods and from different model systems now shed light on the mechanisms of magnitude ratio representations. A coding scheme for proportions has emerged that is remarkably reminiscent of the representation of absolute number. These novel findings suggest a sense for ratios that grants the brain automatic access to proportions independently of language and the format of presentation.     

Comparison of the Family Therapy Educational and Experience Requirements for Licensure or Certification in Six Mental Health Disciplines

In a review of literature on clinical licensure programs and certified mental health disciplines, no studies specifically compared didactic methods and clinical training standards for family-based interventions. Consequently, consumers and insurers of these services have no basis from which to evaluate the relative competency of each of the mental health disciplines in providing family-based interventions. This study used content analysis to examine the amount of family based training that is required by six core mental health disciplines (Clinical Psychology, Psychiatry, Psychiatric Nursing, Professional Counseling, Marriage and Family Therapy, and Social Work) in each of the 50 United States. Results indicate that a marriage and family therapist is required to have three times more family therapy coursework than any other professional mental health discipline. Also, before becoming licensed a marriage and family therapist, must complete 16 times more face-to-face family therapy hours than a mental health professional from any other discipline. Implications for consumers and practitioners are discussed.     

Divergent Reactions to the Terror of Terrorism: Personal Need for Structure Moderates the Effects of Terrorism Salience on Worldview-Related Attitudinal Rigidity

The current studies explore how individual differences in personal need for structure (PNS) influence the extent to which people respond to terrorism threats with cultural worldview-related attitudinal rigidity. PNS was measured, terrorism salience manipulated, and British participants' attitudes toward an essay arguing against the British adoption of the Euro (Study 1) or American participants' attitudes toward an essay arguing for a nontraditional approach to the Thanksgiving meal (Study 2) were assessed. Terrorism salience, relative to a control condition, increased liking of the anti-Euro position and decreased liking for a nontraditional approach to Thanksgiving for those high in PNS. The reverse pattern was found for those low in PNS. Theoretical and applied implications are considered.     

Encontrar problemas y creatividad

RESUMEN

En este artículo se expone un modelo teórico para explicar la creatividad artística. Tradicionalmente han existido dos perspectivas principales para explicar el proceso creador en la psicología: La primera es la tradición racional, la segunda la asociativa. Una tercera vía, crítica con las dos anteriores, es la Gestáltica. Se revisan estas teorías sobre la creatividad, así como, la teoría hemostática y psicoanalítica, y se propone un nuevo modelo teórico, que recoge facetas de las teorías anteriores y las influencias de la psicología cognitiva actual. En este trabajo nos centramos en el proceso creativo en el arte, como proceso creador que experimenta conflictos emocionales, de percepción y pensamiento, y a través de una resolución simbólica restablece de nuevo el equilibrio.     

Nonverbal signals speak up: Association between perceptual nonverbal dominance and emotional intelligence

Emotional communication uses verbal and nonverbal means. In case of conflicting signals, nonverbal information is assumed to have a stronger impact. It is unclear, however, whether perceptual nonverbal dominance varies between individuals and whether it is linked to emotional intelligence. Using audiovisual stimulus material comprising verbal and nonverbal emotional cues that were varied independently, perceptual nonverbal dominance profiles and their relations to emotional intelligence were examined. Nonverbal dominance was found in every participant, ranging from 55 to 100%. Moreover, emotional intelligence, particularly the ability to understand emotions, correlated positively with nonverbal dominance. Furthermore, higher overall emotional intelligence as well as a higher ability to understand emotions were linked to smaller reaction time differences between emotionally incongruent and congruent stimuli. The association between perceptual nonverbal dominance and emotional intelligence, and more specifically the ability to understand emotions, might reflect an adaptive process driven by the experience of higher authenticity in nonverbal cues.     

Emotional,behavioral, and cognitive factors that differentiate obsessive-compulsive disorder and other anxiety disorders in youth

Abstract

The current study examined specific emotional, behavioral, and cognitive variables that may distinguish obsessive-compulsive disorder (OCD) from generalized anxiety disorder (GAD), social phobia (SoP), and separation anxiety disorder (SAD) in youth. Youth with OCD (n=26) and other anxiety disorders (ADs; n=31), aged 7–12 years (56.1% males), and their parents participated. The study compared the two anxious groups on levels of emotional, behavioral, and cognitive functioning, as well as impairment associated with the disorder. Results indicated that in comparison to youth with GAD, SoP, or SAD, youth with OCD were found to have poorer emotion regulation skills, as well as greater oppositionality, cognitive problems/inattention, and parent impairment associated with the disorder. The findings suggest that there are unique characteristics of OCD that may differentiate this disorder from other ADs in youth. Potential clinical implications and directions for future research are discussed.     

Children's Pets and Adults' Self-Concepts

Self-concepts of adults were related to the age when they had their first pet. The Tennessee Self Concept Scale (TSCS) (Fitts, 1965) Total Positive self-concept scores were higher if subjects were under 6 years or over 10 years old than if they were between 6 and 10 years old when they had their first pet. Similar results were found for the TSCS Physical and Social subscales. Whereas gender effects were also found, no significant pet ownership or other childhood Companion Animal Bonding Scale (Poresky, Hendrix, Mosier, & Samuelson, 1987) effects were found.     

An impossibility theorem for amalgamating evidence

Amalgamating evidence of different kinds for the same hypothesis into an overall confirmation is analogous, I argue, to amalgamating individuals’ preferences into a group preference. The latter faces well-known impossibility theorems, most famously “Arrow’s Theorem”. Once the analogy between amalgamating evidence and amalgamating preferences is tight, it is obvious that amalgamating evidence might face a theorem similar to Arrow’s. I prove that this is so, and end by discussing the plausibility of the axioms required for the theorem.
