An Influence of Product and Brand Name on Positive Affect: Implicit and Explicit Measures

Results of two studies indicated that tasting a familiar product designed to be refreshing (iced tea), without knowledge of the brand, induced positive affect, as did the gift-of-candy (not consumed) induction, used in many previous studies. As compared to controls, these participants showed more positive affect as reflected by 5 implicit measures and 2~explicit ratings of the refreshingness and pleasingness of the product. They performed significantly better on items from the Remote Associates Test (a test of creativity), generated more unusual and more pleasant first associates to a randomly selected letter of the alphabet, and to neutral words (the implicit measures). Results also indicated that similar affect did not arise when participants tasted a less liked, unfamiliar, brand of iced tea, without knowledge of the brand. However, when the brand name (a known brand) of that tea was presented with the less liked product sample, people who tasted that same tea showed positive affect responses on the implicit measures of affect and also explicitly rated the tea as more refreshing and pleasing than the unbranded version of the same tea.     

Comparing Performance Standards on the Retention of Words Read Correctly Per Minute

To measure retention of oral reading fluency, three students attending a learning support classroom used a repeating reading strategy with two passages. Each student read one passage to a high performance standard and the other passage to a lower performance standard. Results show it took the students more practice to reach the higher performance standard in regards to both calendar days and practice trials. The retention measures revealed all students had comparable decrements with words read correctly per minute for both the high and low performance standards even though practice varied. During the last retention interval 3½ months after obtaining the performance standard, all students demonstrated the highest terminal frequency of words read correctly per minute in the high performance standard condition.     

A review of the methods used to describe and measure aggressive behaviour in physiological studies

A review of the methods used to study behaviour in a number of experiments investigating the physiology of aggression highlights in the following problems: 1) the narrow range of species studied, 2) the inappropriate conditions in which animals are often housed for observation, 3) the inappropriate stimuli used to elicit aggressive responses in some cases, and 4) the lack of adequate detail with which behaviour is often recorded and analysed. It is stressed that without better techniques for studying behaviour, many questions about the organisation of aggression will remain unanswered.     

Negative problem orientation (Part II): construct validity and specificity to worry

Negative problem orientation, a dysfunctional set of attitudes related to problem-solving ability, has been implicated as a process variable in several psychological disorders, notably depression and generalized anxiety disorder (GAD). The goal of the present study was two-fold: (1) to further examine the construct validity of a new measure of negative problem orientation, the negative problem orientation questionnaire (NPOQ), through its relationship to conceptually similar variables, and (2) to investigate the specificity of negative problem orientation to worry, the cardinal feature of GAD, compared to depression. The sample consisted of 148 university students who completed six questionnaires, the NPOQ and measures of worry, depression, pessimism, self-mastery, and neuroticism. Multiple hierarchical regressions revealed that when entered in the last step following demographic information and personality variables (pessimism, self-mastery, and neuroticism), the NPOQ accounted for 5.6% of the variance in worry scores compared to 1.6% of the variance in depression scores. It was concluded that the NPOQ shows evidence of construct validity, and that the process variable of negative problem orientation appears to have greater specificity to worry than depression. Implications for the understanding of worry and GAD are discussed.     

The interactive effects of conscientiousness, work effort, and psychological climate on job performance

Historically, conscientiousness-performance relationships have been modest, suggesting the need to examine theoretically-relevant moderating variables. Based on theory and empirical research suggesting that performance variance is maximally predicted in the presence of person and situation variables, we examined the moderating potential of work effort and psychological climate on the conscientiousness-performance relationship. Data gathered from 139 predominately part-time restaurant employees revealed that conscientiousness predicted performance in the simultaneous presence of high levels of work effort and positive psychological climate. Conversely, conscientiousness had no empirical association with performance when coupled with other combinations (e.g., high-negative; low-positive; low-negative) of work effort and psychological climate. Implications for research, strengths, limitations, and directions for future research are discussed.     

Anchoring effects on performance judgments

Three studies were conducted investigating the effects of irrelevant anchors on performance judgments. Both a lab and field study demonstrated that an alternative anchoring manipulation that did not involve an explicit comparative question had effects on performance judgments similar to a traditional anchoring manipulation. The final study examined whether the anchoring effects were more likely when the anchor was highly applicable to the final judgment. The results indicated that both highly applicable and low applicable anchors produced an anchoring effect, but the highly applicable anchors had a larger effect on performance judgments. Evidence was also found for asymmetrical anchoring effects. In two of the three studies, high anchors increased performance judgments relative to the control group, whereas low anchors were not significantly different from the control group.     

The effects of total sleep deprivation on semantic priming: Event-related potential evidence for automatic and controlled processing strategies

There is general consensus that performance on a number of cognitive tasks deteriorates following total sleep deprivation. At times, however, subjects manage to maintain performance. This may be because of an ability to switch cognitive strategies including the exertion of compensatory effort. The present study examines the effects of total sleep deprivation on a semantic word priming task. Word priming is unique because it can be carried out using different strategies involving either automatic, effortless or controlled, effortful processing. Twelve subjects were presented with word pairs, a prime and a target, that were either highly semantically associated (cat…dog), weakly associated (cow…barn) or unassociated (apple…road). In order to increase the probability of the use of controlled processing following normal sleep, the subject’s task was to determine if the target word was semantically related to the prime. Furthermore, the time between the offset of the prime and the onset of the target was relatively long, permitting the use of an effortful, expectancy-predictive strategy. Event-related potentials (ERPs) were recorded from 64 electrode sites. After normal sleep, RTs were faster and accuracy higher to highly associated targets; this performance advantage was also maintained following sleep deprivation. A large negative deflection, the N400, was larger to weakly associated and unassociated targets in both sleep-deprived and normal conditions. The overall N400 was however larger in the normal sleep condition. Moreover, a long-lasting negative slow wave developed between the offset of the prime and the onset of the target. These physiological measures are consistent with the use of an effortful, predictive strategy following normal sleep but an automatic, effortless strategy following total sleep deprivation. A picture priming task was also run. This task benefits less from the use of a predictive strategy. Accordingly, in this task, ERPs following the target did not differ as a function of the amount of sleep.

Parent and Teacher Ratings of Attention-Deficit/Hyperactivity Disorder in Preschool: The ADHD Rating Scale-IV Preschool Version

Efforts for early identification and intervention for children with AD/HD have necessitated the development of rating scales of behavior for the preschool population. The standardization, reliability, and validity data were presented for the ADHD Rating Scale-IV Preschool Version. Parent and teacher ratings were collected on 902 and 977 children 3 to 5 years of age, respectively. Raw scores for the Inattention, Hyperactivity/Impulsivity and Total scores were converted to T-Scores and percentile ranks. Reliability coefficients ranged from 0.80 to 0.95 indicating good test–retest reliability. Concurrent validity with the Conners Teacher Rating Scales: Revised-Short and Conners Parent Rating Scale: Revised-Short ranged from 0.54 to 0.96. The ADHD-Rating Scale-IV appears to be a reliable, valid and user friendly measure for screening preschoolers with behavior problems. Future research is needed to validate its widespread use as a screening and diagnostic tool.     

Testing 1, 2, 3, …4? The personality of repeat SAT test takers and their testing outcomes

The current study considered the correlates of test retaking. In particular, the personality trait of neuroticism was proposed to be related to retaking the SAT test. Results revealed that, accounting for initial SAT score and the other Big Five factors of personality, neuroticism predicted the number of times an individual took the SAT before attending college. Further, the results of a latent growth model indicated that, for those who retook the SAT, test scores showed improvement over time. None of the Big Five predicted changes in SAT scores. Results are discussed in light of the possible benefits of high levels of neuroticism for SAT score improvement.
