Measurement Models for the Subjective Utility of Children1

Measurement models of subjective child utility were derived from theoretical typologies of expected consequences of children. Maximum likelihood estimates of the goodness-of-fit of each model to observed convariation among 18 indicators of subjective child utility were obtained, using data from 349 wives and 349 husbands. The best-fitting models included three distinct factors: personal rewards, personal costs, and normative rewards.     

The relationship between state anxiety and depressed mood: A validity study

The validity of the A-State Scale of the State-Trait Anxiety Inventory and the Zung Self-Rating Depression Scale was assessed using data from a general health survey. Depression and anxiety states were found to coexist, however, evidence from a factor analysis, showing items from the two tests loaded on separate factors, demonstrated that these states can be measured independently. Both the A-State and the Zung Scales were found to comprise two factors, and for each scale, one factor consisted of positively phrased items, and the other of negative items. The implications of these findings for the construct validity of the two scales are discussed.     

Boundary conditions in the common-factor-space,in the factorial analysis of ability

The author arrives at a simple rule for ascertaining when a matrix of correlations, with communalities reducing it to minimum rank, cannot be analyzed into factors such that every column of loadings has at least as many zeros as the number of common factors, as required by Thurstone. A more exact but arithmetically tedious rule is also deduced from Ridley Thompson's boundary conditions, and a correction is made to the latter.     

Comparison of consonantal and vocalic cues in selective adaptation

The acoustic cues to the phonetic identity of diphthongs normally include both spectral quality and dynamic change. This fact was exploited in a series of selective adaptation experiments examining the possibility of mutual adaptive effects between these two types of acoustic cues. One continuum of syllables varying from [εi] to [εd] and another varying from [ε] to [εi] were synthesized; endpoint stimuli of both series used as adaptors caused identification boundaries to be shifted. Cross-series adaptation was also attempted on the [ε?εi] stimuli, using [?], [∞], and [ai]. Only [ai] proved effective as an adaptor, suggesting the mediation of a rather abstract auditory level of similarity. The results argue strongly against interpretations in terms of feature detectors, but appear compatible with an “auditory contrast” explanation, which might in turn be incorporated within adaptation level theory in the form recently discussed by Restle (1978). The cross-series results further suggest that selective adaptation might be used to quantify the perceptual distance between auditory cues in speech.     

Effects of UCS intensity and postpeak acquisition trials on classical conditioning of the SCR

The present study examined the effects of UCS intensity and number of postpeak acquisition trials on classical conditioning and extinction of the SCR. A 2 × 3 design was employed in which subjects received either a 1, 2, or 4 mA shock UCS and either two or 16 acquisition trials beyond the peak CR. While conditioning was demonstrated during acquisition, there was no relationship between strength of conditioning and intensity of UCS. The phenomenon of stronger resistance to extinction following fewer acquisition trials (e.g., two past the peak CR) than with many (e.g., 16 past the peak CR) was demonstrated only for the groups that were conditioned with the 4 mA UCS. Resistance to extinction varied positively with UCS intensity, but only for the subjects who received two postpeak acquisition trials. Sixteen trials beyond the peak CR resulted in the UCS intensity having little or no effect on resistance to extinction.     

Functional analysis and treatment of problem behavior evoked by noise.

We conducted a four‐part investigation to develop methods for assessing and treating problem behavior evoked by noise. In Phase 1, 7 participants with developmental disabilities who were described as being hypersensitive to specific noises were exposed to a series of noises under controlled conditions. Results for 2 of the participants verified that noise was apparently an aversive event. In Phase 2, results of functional analyses indicated that these 2 participants' problem behaviors were maintained by escape from noise. In Phase 3, preference assessments were conducted to identify reinforcers that might be used during treatment. Finally, in Phase 4, the 2 participants' problem behaviors were successfully treated with extinction, stimulus fading, and a differential‐reinforcement‐of‐other‐behavior (DRO) contingency (only 1 participant required DRO). Treatment effects for both participants generalized to their home environments and were maintained during a follow‐up assessment. Procedures and results were discussed in terms of their relevance to the systematic assessment of noise as an establishing operation (EO) and, more generally, to the identification of idiosyncratic EO influences on behavior.     

Eyewitness identification evidence and innocence risk

It is well known that the frailties of human memory and vulnerability to suggestion lead to eyewitness identification errors. However, variations in different aspects of the eyewitnessing conditions produce different kinds of errors that are related to wrongful convictions in very different ways. We present a review of the eyewitness identification literature, organized around underlying cognitive mechanisms, memory, similarity, and decision processes, assessing the effects on both correct and mistaken identification. In addition, we calculate a conditional probability we call innocence risk, which is the probability that the suspect is innocent, given that the suspect was identified. Assessment of innocence risk is critical to the theoretical development of eyewitness identification research, as well as to legal decision making and policy evaluation. Our review shows a complex relationship between misidentification and innocence risk, sheds light on some areas of controversy, and suggests that some issues thought to be resolved are in need of additional research.     

Positive emotion infusions of elevation and gratitude: Increasing help-seeking intentions among people with heightened levels of depressive symptomatology

Three online studies assessed a new approach for increasing help seeking among people with depressive symptomatology (i.e. a positive emotion infusion, PEI). A PEI refers to the induction of positive emotion such that people’s mindsets – including perceptions of help-seeking – are temporarily altered. Study 1 (n = 382) indicated that help-seeking intentions are negatively correlated with depressive symptomatology and positively correlated with elevation and gratitude. Studies 2 and 3 implemented fully randomized experimental designs. In Study 2, two elevation-based (Study 2a, n = 285) and two gratitude-based (Study 2b, n = 338) emotion inductions increased levels of elevation and gratitude, respectively. Results of Study 3a (n = 390) indicate a causal relationship between experiencing the story-based elevation induction and increased help-seeking intentions. The two gratitude-based PEIs (Study 3b, n = 466) were unsuccessful at influencing help-seeking; auxiliary analyses indicate the possibility of iatrogenic effects. Overall, the potential of PEIs was indicated, as was need for caution.     

“Doing Gender” and “Doing Religion” in Science: A Cross-National Examination

Women tend to be both underrepresented in science and overrepresented in organized religion, yet the connection between these two phenomena is rarely examined. With survey data collected among 6,537 biologists and physicists from four national contexts—the United States, the United Kingdom, Italy, and India—we test whether science as a social field shapes religious expressions and attitudes differently for men and women. Findings reveal a religious gender gap in India and Italy but not in the United States and the United Kingdom. Further, except in Italy, men had higher odds of perceiving religion and science to be in conflict, believing that their colleagues have a negative attitude about religion, and reporting that science made them less religious. Evidence suggests that men in science may disproportionately internalize normative pressures to masculinize by eschewing religion. Our findings have implications for selection into academic science and the practice of religion among men and women in science.
