An exploratory study of students' use of cell phones, texting, and social networking sites

In a sample of 128 undergraduate students, a higher frequency of texting to others was associated with finding the relationships with those others less fulfilling. Similarly, having more social network "friends" was associated with finding the relationships with those individuals less fulfilling.

To carry or not to carry — Is this the question? Disentangling the carry effect in multi-digit addition

Recent research has suggested addition performance to be determined by both the need for a carry operation and problem size. Nevertheless, it has remained debatable, how these two factors are interrelated. In the current study, this question was pursued by orthogonally manipulating carry and problem size in two-digit addition verification. As the two factors interacted reliably, our results indicate that the carry effect is moderated by number magnitude processing rather than representing a purely procedural, asemantic sequence of processing steps. Moreover, it was found that the carry effect may not be a purely categorical effect but may be driven by continuous characteristics of the sum of the unit digits as well. Since the correct result of a carry problem can only be derived by integrating and updating the magnitudes of tens and units within the place-value structure of the Arabic number system, the present study provides evidence for the idea that decomposed processing of tens and units also transfers to mental arithmetic.     

“End-of-life” biases in moral evaluations of others

When evaluating the moral character of others, people show a strong bias to more heavily weigh behaviors at the end of an individual’s life, even if those behaviors arise in light of an overwhelmingly longer duration of contradictory behavior. Across four experiments, we find that this “end-of-life” bias uniquely applies to intentional changes in behavior that immediately precede death, and appears to result from the inference that the behavioral change reflects the emergence of the individual’s “true self”.

Culture and Probability Judgment

Many, if not most, real-life decisions depend heavily on judgments, which are opinions as to what was, is, or will be the state of some relevant aspect of the world. Thus, for instance, physicians’ medical treatment decisions are often predicated on judgments as to the true cause of the patient’s symptoms, and jurors’ verdicts rest on their beliefs about whether the defendant actually committed the crime in question. Studies have shown that the kinds of judgments that inform people’s decisions can differ substantially and surprisingly according to the cultural backgrounds (e.g., Chinese versus Japanese versus American) of those rendering the judgments, particularly judgments expressed as probabilities (e.g., “There’s a 75% chance that that will happen”). This article reviews major cultural variations in key characteristics of probability judgments (e.g., their overconfidence) and why those differences exist. It also discusses the theoretical and practical implications of the findings, including for collaborations among decision makers from distinct cultures.     

The structure of the relationship between attention and intelligence

The relationship between attention and general intelligence was investigated considering the different types of attention: alertness, sustained attention, focused attention, attentional switching, divided attention, attention according to the supervisory attentional system, attention as inhibition, spatial attention, attention as planning, interference, attention as arousal, and attention according to the assessment tradition. In a sample of 197 participants the relationship of attention and intelligence was investigated by means of structural equation modeling. The results revealed that each type of attention was substantially related to intelligence on the latent level. Furthermore, a high degree of overlap in predicting intelligence was observed for the various types of attention. Comprehensive models based on resources theory and Posner's dimensions were also investigated. The best model of the relationship between attention and intelligence included two first-order and one second-order latent variables of attention and one of intelligence. It predicted 32% of the variance of intelligence.
