A concussion is a brain injury that affects cognitive, emotional, behavioral, physical, and sleep/energy patterns. The Centers for Disease Control and Prevention (CDC) estimate that approximately 1.6 to 3.8 million sports and recreational concussions occur each year. Countless more children sustain concussions from nonsports activities such as…

Objective: This research examined why smokers receiving combination medication for smoking cessation are more likely to quit smoking than are those who receive either single agent (monotherapy) or placebo. Method: Data were collected from 1,504 current smokers (58.2% women, 83.9% White; mean age = 44.67 years, SD = 11.08) participating in a…

This study examined the relations between behavioral inhibition, Big Five personality traits, and anxiety disorder symptoms in non-clinical children (n = 147) and clinically anxious children (n = 45) aged 6-13 years. Parents completed the Behavioral Inhibition Questionnaire-Short Form, the Big Five Questionnaire for Children, and the Screen for…

We conducted three experiments to reproduce and extend Perone and Courtney's (1992) study of pausing at the beginning of fixed-ratio schedules. In a multiple schedule with unequal amounts of food across two components, they found that pigeons paused longest in the component associated with the smaller amount of food (the lean component), but only…

This article examines the determinants of eco-friendly electronic good consumption among students at a large Australian university who have been exposed to a marketing campaign, Mobile Muster. Empirical research generally shows younger consumers to be less concerned about the environment. Similar studies demonstrate that peer pressure has a large…

Innatism is the belief that most of the human personality can be determined by genes. This ideology is dangerous, especially when it claims to be scientific. The present study investigates conceptions of 1060 students from Estonia and France related to genetic determinism of some human behaviours. Factors taken into account included students'…

The purpose of this study was to explore the nature of students' mapping and discourse behaviors while constructing causal maps to articulate their understanding of a complex, ill-structured problem. In this study, six graduate-level students were assigned to one of three pair groups, and each pair used the causal mapping software program,…

This article reviews the relationship between the conservative newspaper "The Australian" and the development of a national history curriculum in Australia. The lead author surveyed the major Australian press in the five-year period between 2007 and 2012 and found clear patterns of difference between "The Australian" and other…

Serotonin is a fundamental neuromodulator in both vertebrate and invertebrate nervous systems, with a suspected role in many human mental disorders. Yet, because of the complexity of serotonergic function, researchers have been unable to agree on a general theory. One function suggested for serotonin systems is the avoidance of threat. We propose…

Infants intentionally communicate with others from before their 1st birthday. But there is some question about how they understand the communicative process. Do they understand that for their request to work the recipient must both understand the request and be cooperatively disposed to fulfill it? On the basis of the study by Shwe and Markman…

The study described the interaction between therapist and clients in a group intervention with two mothers and a grandmother. Five out of thirteen taped sessions were designated for analysis. Main results: a) therapist's categories that stood out: approval, recommendation, interpretation, information and information request; b) clients' categories…

In recent years there has been a striking shift in both academic and popular discourse on the subject of male-female differences. It is increasingly common for biological explanations to be proposed for differences that had previously been treated by most investigators as effects of socio-cultural factors. This article critically examines the…

Theory of mind, the capacity to understand and ascribe mental states, has traditionally been conceptualized as analogous to a scientific theory. However, recent work in philosophy and psychology has documented a "side-effect effect" suggesting that moral evaluations influence mental state ascriptions, and in particular whether a behavior is…

The present experiment examined the effects of acute and daily cocaine on spontaneous behavior patterns of pigeons. After determining the acute effects of a range of doses, 9 pigeons were divided into three groups that received one of three doses of cocaine daily, either 1.0, 3.0, or 10.0 mg/kg cocaine. Measures were taken of spontaneous…

This study addresses the frequency and the distribution of reported lying in the adult population. A national survey asked 1,000 U.S. adults to report the number of lies told in a 24-hour period. Sixty percent of subjects report telling no lies at all, and almost half of all lies are told by only 5% of subjects; thus, prevalence varies widely and…
