The effects of instructional cues on performance and mechanics during a gross motor movement

Externally focused instructions specific to performance have shown to improve body mechanics (Gokeler et al., 2015; Welling, Benjaminse, Gokeler, & Otten, 2016). However, the effect of using an external focus instruction may have been more profound if the content of the instruction had been relevant to mechanics. Therefore, the present study examined the effects of externally focused instructions specific to performance and externally focused instructions specific to body mechanics on mechanics and performance. Twenty-four adults (n = 12 males; n = 12 females) performed a series of drop jumps following external focus cues that were specific to performance and landing mechanics. Participants completed a drop jump followed by a maximal effort vertical jump. The initial contact, maximal angle, and range of motion at the knee in the sagittal and frontal plane motion were measured for mechanics and the height of the second vertical jump was measured for performance. The results suggest external focus instructions specific to performance are beneficial for performance, but not for improving landing mechanics. This suggests that external focus instructions must be specific to the contents of the instruction.     

Positive impression management and its influence on the Revised NEO Personality Inventory: a comparison of analog and differential prevalence group designs

Participants (n = 22) completed the Revised NEO Personality Inventory (NEO PI-R) as part of an authentic job application. Protocols produced by this group were compared with "analog" participants (n = 23) who completed the NEO PI-R under standard instructions and again under instructions designed to mimic the test-taking scenario of the job applicants (the "fake-good" condition). Participants completing the NEO PI-R under fake-good instructions and the job applicants scored lower on the Neuroticism and higher on the Extraversion scales than did the participants responding under standard instructions. Analog participants in the fake-good condition scored higher on the Extraversion and lower on the Agreeableness scales than did the job applicants. These results suggest that outcomes from analog designs are generalizable to real-world samples where response dissimulation is probable.     

Effects of an expert-modeled attentional focus cue structure on skilled jump rope performance and learning

Instructions that direct attention externally have been shown to enhance motor performance. However, research on skilled performers and on learning effects has produced some distinct findings. Further, many studies have presented an overly simplistic view of attention and learning, such that all-internal focus protocols are contrasted with all-external focus protocols. Contrary to this approach, skilled performers have reported adopting combined focus strategies, revealing the need to test more realistic instructional protocols. The current study provided an experimental test of focus instructions that were modeled after the strategies of elite jump rope athletes. Four groups of skilled jump rope athletes practiced novel skills under various focus instructions. The internal focus (IF) and external focus (EF) groups were given traditional internal and external focus instructions, respectively. The expert modeled (EM) group was given a set of instructions that were based on experts' reported focus strategies. The expert modeled-autonomous (EM-A) group was allowed to choose how they used each of the expert-modeled instructions. All groups completed a baseline assessment, four practice sessions, and a learning assessment. Results of a chi-square test of independence revealed no relationship between group assignment and performance during baseline or practice. There was a significant relationship between group assignment and performance during the learning assessment (p < .05). Specifically, the IF group performed below expected values while the EM group performed better than expected. Findings support previous research showing learning detriments associated with internal focus instructions and also provide new insight into the advantages of using instructional approaches that are modeled after experts' strategies. Implications and suggestions for future research are discussed.     

Effect of symptom information and intelligence in dissimulation: an examination of faking response styles by inmates on the Basic Personality Inventory

This study employed the Basic Personality Inventory (BPI) to differentiate various types of dis-simulation, including malingered psychopathology and faking good, by inmates. In particular, the role of intelligence in utilizing symptom information to successfully malinger was examined. On admission to a correctional facility, 161 inmates completed the BPI under standard instructions and then again under instructions to fake good (n = 55) or to malinger psychotic (n = 35), posttraumatic stress disorder (n = 36), or somatoform (n = 35) psychopathology. Unlike symptom information, intelligence evidenced some support for increasing inmates' effectiveness in malingering, although there was no relationship between higher intelligence and using symptom information to successfully evade detection. Overall, the BPI was more effective in detecting malingered psychopathology than faking good. Implications for the detection of dissimulation in correctional and forensic settings are discussed.     

The Influence of Attentional Focus on Balance Control over Seven Days of Training

This study examined the training effect of attentional focus (external focus, internal focus, or no focus instructions) on a dynamic balance task. Participants completed baseline balance testing, seven consecutive days of dynamic balance board training, and retention testing 24 hours after the last session. The novel finding of this study was the presence of a training effect on balance control when adopting an external focus relative to an internal focus or no focus instructions. Further, we report the unique observation that more patterned behavior was adopted regardless of the focus instructions. These findings provide insight into how instructions can be altered to enhance human balance control and complement the constrained-action hypothesis.     

Be Careful What You Ask For: Effects of Response Instructions on the Construct Validity and Reliability of Situational Judgment Tests

The aim of this study was to examine how six different types of situational judgment test (SJT) instructions, used frequently in practice, influence the psychometric characteristics of SJTs. The six SJT versions used the exact same items and differed only in their instructions; these versions were administered in two phases. Phase I was a between–subjects design (n= 486) that had participants complete one version of the SJTs. Phase II was a within–subjects design (n= 231) held several weeks later that had participants complete all six versions of the SJTs. Further, 146 of these individuals completed both phases, allowing for an assessment of test–retest reliability. A variety of objective and subjective criteria were collected, including self and peer ratings. Results indicated that instructions had a large effect on SJT responses, reliability, and validity. In general, instructions asking what one ‘would do’ showed more favorable characteristics than those that asked what one ‘should do’. Correlations between these two types were relatively low despite the fact that the same items were used, and criterion–related validities differed substantially in favor of the ‘would do’ instructions. Overall, this study finds that researchers and practitioners must give careful consideration to the types of SJT instructions used; failing to do so could influence criterion–related validity and cloud inferences of construct validity.     

The effect of testing instructions for handling social desirability on the Eysenck personality questionnaire

The Hebrew version of the Revised Eysenck Personality Questionnaire (EPQ-R) was administered to two groups. One group was given special ‘feedback’ instructions intended to make subjects aware of the extent of their distortions due to responding in a socially desirable direction, and of the possibility of detection of such distortions. The other group was given ordinary standard instructions. There was a substantial change in the mean of the Lie (L) scale, a moderate change in the Neuroticism (N) scale and no significant change in the mean of the Extraversion (E) and Psychoticism (P) scales. The reliability estimates and factor pattern showed a marked improvement of the P scale and some improvement of the N and L scales, and no effect on the E scale.     

Identifying Positive Dissimulation by Substance-Abusing Individuals on the Personality Assessment Inventory: A Cross-Validation Study

The accuracy of a classification equation (which combined scores on the Drug Problems, Alcohol Problems, and Positive Impression scales from the Personality Assessment Inventory [PAI], Morey, 1991), developed by Fals-Stewart (1996) to identify test-taking response sets among substance-abusing individuals, was evaluated. As in the Fals-Stewart (1996) study, three groups of participants completing the PAI were assessed: (a) substance-abusing patients administered the inventory under standard instructions (n = 25); (b) substance-abusing patients asked to respond defensively (n = 25) combined with a group of individuals suspected of abusing drugs, referred for art evaluation by the criminal justice system, who had reasons to conceal their drug use (n = 25); and (c) non-substance-abusing respondents administered the test under standard instructions (n = 25). Significant validity shrinkage in the classification equation was found when applied to the new sample; only 68% of participants were correctly classified into their respective groups, compared to 82% of participants correctly assigned in the Fals-Stewart (1996) investigation.     

Detecting and Discriminating Between Random Responding and Overreporting on the MMPI-A

The utility of traditional validity scales in detecting random responding and overreporting on the MMPI-A and in discriminating between these two response sets was investigated in a sample of 89 clinical and nonclinical adolescents aged 14 to 17 years. The overreporting group consisted of 24 nonclinical adolescents instructed to complete the MMPI-A as if they were trying to create an impression of psychological disturbance. The random group included 20 nonclinical adolescents instructed to complete the MMPI-A answer sheet without access to the test booklet. Clinical (n = 20) and nonclinical (n = 25) standard groups completed the MMPI-A under the standard instructions. Results showed that validity scales designed to detect random responding and overreporting on the MMPI-A were quite effective in doing so. Significant differences between groups and high classification rates were noted. In addition, the VRIN scale was found to be sensitive only to random responding, whereas Scale F was sensitive to both random responding and overreporting. Scale L also was found to be sensitive to random responding, and support for the utility of the F - K index in identifying overreported adolescent profiles was obtained.     

Effect of response distortion on the assessment of divergent facets of psychopathy

Recent evidence suggests that the Psychopathic Personality Inventory (PPI) is composed of two orthogonal factors, one representing traits such as dominance and low anxiety (PPI-I) and a second that reflects more socially deviant aspects of psychopathy (PPI-II). To assess whether response sets differentially affect these factors, the present research reanalyzed data from two dissimulation studies in which college students completed the PPI both honestly and with instructions either to "fake good" (n = 186) or "fake bad" (n = 143). PPI-II scores decreased significantly in the fake-good condition (d = -.86) and increased significantly when faking bad (d = 2.65). PPI-I scores were unaffected by attempts to feign serious psychopathology (d = .10) and actually increased in the fake-good condition (d = .53). These findings significantly qualify previous conclusions about the effect of response distortion on the PPI.     

Expert and Target Scoring: Their relation,corresponding test instructions,and their effects on the construct validity of the video‐based social understanding test (VSU)

This study investigated the relation between expert and target scoring of a video‐based social understanding test (VSU) under two different types of instructions (internal and observer). The effects of the scoring methods and instructions on the VSU's construct validity were also examined. A total of 529 pilot applicants completed the VSU (some with internal and some with observer instructions), cognitive ability and knowledge tests, and a personality questionnaire. A subsample (n = 132) completed the VSU again with the other instructions and participated in an assessment center (AC). The two scores were moderately correlated; correlations decreased when the instructions were considered. Neither expert nor target scores showed convergent validity with AC variables; none of the scoring‐instruction combinations showed significant associations with the remaining measures.     

“This phone saved my life”: Older persons’ experiences and appraisals of an mHealth intervention aimed at addressing loneliness

This qualitative study aimed to explore older persons’ experiences and appraisals of the utility of an mHealth intervention for reducing their sense of loneliness. Participants (n = 13; 86.42% females; age range 65 to 87 years) received training in the use of a smartphone and a social networking application (WhatsApp). Following the intervention, they completed a focus group discussion. For data triangulation, participants shared their social media postings. Content analysis of the focus group discussion and social media data indicated that the mobile device was used to mitigate perceptions of loneliness and isolation, thus facilitating social network building, enhancing self-efficacy, and improving cognitive flexibility. Mobile phones and a social networking application appear to reduce loneliness experienced by the elderly.     

Support Group Needs for People Living with HIV and AIDS (PLWHA) in Communities around Durban,South Africa

The study constructed a participant centred perspective of what members of a support group for people living with HIV and AIDS (PLWHA) desired from their group meetings. The study sample (n = 34) was from three support groups of PLWHA in a province of South Africa (males = 7, female = 27, mean age = 34.2 years, SD = 6.8 years). Participants completed a brief survey and participated in focus group discussion on views on the ideal support group, actual experience with the support group, and solutions for effective support groups. Findings suggest most members of the support group experienced a high degree of stigma at home and needed a so-called ‘safe space’ to escape to and discuss issues with people experiencing similar problems. Respondents wanted to acquire skills to allow them to help themselves and others in the community. They also desired HIV education so that they could properly understand the virus and help the community understand it to reduce stigma.     

Effects of orienting instructions, monetary incentives, and sex of listeners on listening comprehension

The study investigated the effects of orienting instructions, monetary incentives, and sex of the listener on performance on a test of listening comprehension. Neither orienting instructions nor monetary incentives resulted in significant differences, but undergraduate men (n = 64) scored significantly higher than the women (n = 56) on the listening comprehension test.     

Evaluation of content and vocal style in relaxation instructions

The relative contributions of content and vocal style in relaxation instructions were studied in vivo. Eighty adult dental patients, 40 males and 40 females, who required two amalgam dental restorations were randomly assigned to four conditions (10 males and 10 females in each): a control group in which the restorations were completed in the typical fashion; a group who listened to standard relaxation instructions during the dental procedure; a group who listened to relaxation instructions presented in a conversational tone and pace: and a group who listened to a travelogue presented in a calm, quiet voice at a slow pace. Several cognitive self-rating measures and electrodermal response measures were obtained. The pattern of results suggested that content may be somewhat more important than style in relaxation instructions. However, both appear to be necessary to produce effective relaxation.     

When it does hurt to try: adult age differences in the effects of instructions on implicit pattern learning

Trying to learn sometimes impairs implicit learning of artificial grammars and of control systems. We asked whether such negative effects of trying also occur in implicit learning of subtle sequential regularities and whether such effects vary with adult age. Young (n=12, age=20–23) and older (n=24, age=60–80) adults completed an alternating serial response time task in which predictable pattern events alternated with random ones in a visual/spatial display. Half of the participants were informed about the pattern and were instructed to try to discover it (intentional instructions), and half were not (incidental instructions). Age-related deficits in implicit learning occurred for both conditions. In addition, for the older group, but not for the younger one, intentional instructions impaired implicit pattern learning. This negative effect of trying to learn demonstrates another similarity among implicit learning tasks, supporting the view that some common processes underlie different forms of implicit learning.     

Validation of a Community Collective Efficacy Scale in an African Context

The aim of this study was to validate a community collective efficacy scale in an African context. An abridged version of the Community Collective Efficacy Scale was validated in a cross-sectional survey design. Participants (N = 1050) from urban (n = 451) and rural (n = 599) areas completed the CCES and other measures of self-efficacy and psychological well-being. Results indicated a Cronbach alpha reliability coefficient of 0.72 and satisfactory inter-item correlations ranging between 0.17 and 0.25. Significant correlations between the CCES and other measures of self-efficacy and psychological well-being indicated good criterion-related validity. Construct validity was supported by confirmatory and exploratory factor analysis. Exploratory factor analysis yielded one factor that relates to a sense of “we-ness”. The CCES thus has good reliability and validity in an African context.     

A measure for the assessment of eating disorders: reliability and validity studies of the Rating of Anorexia and Bulimia interview - revised version (RAB-R)

The Rating of Anorexia and Bulimia interview (RAB) is a Swedish semi-structured interview for clinical and research purposes for a wide range of eating disorder symptoms and related psychopathology. The objectives were to evaluate the reliability and validity of a revised RAB version (RAB-R). The RAB-R was assessed in terms of internal consistency, inter-rater and test-retest reliability, and criterion and convergent validity. Samples included a clinical sample of eating disorder patients (n = 71) and a sample of randomly drawn female controls (n = 31). The RAB-R showed satisfactory internal consistency, inter-rater and test-retest reliability, correlated well with related measures, and discriminated between patients and normal controls. We conclude that the RAB-R is a promising interview instrument and continued evaluation should focus on comparing subgroups of eating disorder patients with other clinical groups.     

Deceptiveness on the PAI: a study of naïve faking with psychiatric inpatients

In this study, we sought to explore the diagnostic accuracy of the Personality Assessment Inventory (PAI; Morey, 1991) Validity scales (Negative Impression Management [NIM] and Positive Impression Management [PIM]) and indexes (Malingering index, Defensiveness index [DEF]; Morey, 1993, 1996; Cashel Discriminant Function; Cashel, Rogers, Sewell, & Martin-Cannici, 1995; and Rogers Discriminant Function [RDF]; Rogers, Sewell, Morey, & Ustad, 1996) to identify differences in profiles completed by psychiatric inpatients under standardized instructions (Time 1) and after random assignment (Time 2) to a fake good (n=21), fake bad (n=20), or retest (n=21) scenario. Repeated measures analysis of variance revealed a significant interaction effect. Whereas the retest group did not show any significant changes on the PAI variables from Time 1 to Time 2, both faking groups showed changes in expected directions. Discriminant function analyses revealed that NIM, RDF, and lower scores on DEF best differentiated between the faking bad and retest groups. PIM was the only nonredundant significant score discriminating the faking good and retest groups. Cutoffs for these scales and indexes established in prior research were supported using diagnostic efficiency statistics. Results suggest that NIM and RDF in faking bad scenarios and PIM in faking good scenarios are most sensitive to unsophisticated attempts to dissimulate by inpatient psychiatric patients.
