Reality monitoring and resistance to forgetting under short delay intervals

In three experiments, participants were asked to perform simple action statements or to imagine performing the actions in a single study session. In a test session that occurred 1 hr, 24 hr, 48 hr (Experiments 1a and 1b), or 1 week later (Experiments 2 and 3), participants were instructed to tell whether the action statement had been carried out or imagined. The primary finding was that, overall, recognition and reality monitoring showed a comparable rate of forgetting. The results add evidence to the hypothesis that, also after long retention delays, discrimination between an internal and an external source may not be inferior to item recognition. A new theoretical proposal to account for these findings is outlined.     

Patient Perceptions of Telephone vs. In-Person <Emphasis Type="Italic">BRCA1/BRCA2</Emphasis> Genetic Counseling

Telephone genetic counseling (TC) for hereditary breast/ovarian cancer risk has been associated with positive outcomes in high risk women. However, little is known about how patients perceive TC. As part of a randomized trial of TC versus usual care (UC; in-person genetic counseling), we compared high risk women’s perceptions of: (1) overall satisfaction with genetic counseling; (2) convenience; (3) attentiveness during the session; (4) counselor effectiveness in providing support; and (5) counselor ability to recognize emotional responses during the session. Among the 554 participants (TC, N?=?272; UC, N?=?282), delivery mode was not associated with self-reported satisfaction. However, TC participants found counseling significantly more convenient than UC participants (OR?=?4.78, 95 % CI?=?3.32, 6.89) while also perceiving lower levels of support (OR?=?0.56, 95 % CI?=?0.40–0.80) and emotional recognition (OR?=?0.53, 95 % CI?=?0.37–0.76). In exploratory analyses, we found that non-Hispanic white participants reported higher counselor support in UC than in TC (69.4 % vs. 52.8 %; OR?=?3.06, 95 % CI?=?1.39–6.74), while minority women perceived less support in UC vs. TC (58.3 % vs. 38.7 %; OR?=?0.80, 95 % CI?=?0.39–1.65). We discuss potential research and practice implications of these findings which may further improve the effectiveness and utilization of TC.     

Let’s be healthy together: Relational motivation for physical health is more effective for women

Four studies examined the role of relationally-autonomous reasons in health behavior (RARHs) and how gender moderates their association with health outcomes. Study 1 (n = 160) involved the development of a measure of RARHs. The results of a factor analysis distinguished RARHs from other types of health reasons. In Study 2, participants (n = 284) completed a survey assessing their relational reasons prior to taking assessments of their body composition and fitness level. In Study 3, participants (n = 577) completed an online survey assessing RARHs, self-construal and health behaviors. The results of Studies 2 and 3 showed that RARHs positively predicted healthy outcomes for females only. In Study 4, participants (n = 72) were asked to complete an online survey, attend an orientation session, keep track of their exercise and nutrition over the course of a week, and attend a follow-up session. The results revealed that having an exercise partner was positively associated with RARHs, and that this in turn predicted reported effort and progress outcomes at the follow-up session for females only. Implications for theories of motivation and gender differences are discussed.     

Work-anxiety-coping intervention improves work-coping perception while a recreational intervention leads to deterioration: Results from a randomized controlled trial

Work-anxieties are costly and need early intervention. The perception of being able to cope with work is a basic requirement for work ability. This randomized controlled trial investigates whether a cognitive behavioural, work-anxiety-coping group (WAG) intervention leads to better work-coping perception than an unspecific recreational group (RG). Heterogeneous people in medical rehabilitation, who were due to return to work, were interviewed concerning their work-anxieties, and either randomly assigned to a WAG (n = 85) or a RG (n = 95). The participants (with an average of 50 years old [range 23–64]; 51% women; 70% workers or employees, 25% academics, 5% unskilled) followed the group intervention for four or six sessions. The perceived work-coping was assessed by self-rating (Inventory for Job-Coping and Return Intention JoCoRi) after each group session. Although participants had a slight temporary decrease in work-coping after group session two (from M₁ = 2.47 to M₂ = 2.28, d_Cohen = ?.22), the WAG led to the improvement of perceived work-coping over the intervention course (from M₁ = 2.47 to M₆ = 2.65, d_Cohen = .18). In contrast, participants from the RG reported lower work-coping after six group sessions (from M₁ = 2.26 to M₆ = 2.02, d_Cohen = ?.18). It is considered that people with work-anxieties need training in work-coping. By focusing on recreation only, this may lead to deterioration of work-coping. Indeed, intervention designers should be aware of temporary deterioration (side effects) when confronting participants with work-coping.     

The Effect of Action Observation Training on Balance and Sit to Walk in Chronic Stroke: A Crossover Randomized Controlled Trial

The aim of this study was to investigate the effects of an action observation training on balance and sit to walk in chronic stroke. Twenty-four chronic stroke patients participated in this study. Participants were randomly allocated to either the landscape imagery observation physical training group (LIOPT) or the action observation physical training group (AOPT). LIOPT observed a landscape picture for 2 min 30 s while the AOPT group observed related video recording. Both groups underwent a physical training session after the observation session for 12 min 30 s and the sessions were repeated twice a day, 3 times a week for 6 weeks. Outcome measures included Time Up and Go Test (TUG), Dynamic Gait Index (DGI), Weight Distribution Index (WDI), and limit of stability (LOS). Between-group and within-group comparisons were analyzed using the Mann-Whitney U test and Wilcoxon signed rank test, respectively. The AOPT and LIOPT groups have shown statistically significant differences in TUG, DGI, WDI, and LOS over time. However, no significant difference was observed in terms of TUG, DGI and WDI, but only in LOS between groups. These findings suggest that action observation training and physical training are effective to improve sit to walk and balance ability of chronic stroke patients.     

When will is not the same as should: The role of modals in reasoning with legal conditionals

Naïve reasoners reject logically valid conclusions from conditional rules if they can think of exceptions in which the antecedent is true, but the consequent is not. However, when reasoning with legal conditionals (e.g., “If a person kills another human, then this person should be punished for manslaughter”) people hardly consider exceptions but evaluate conclusions depending on their own sense of justice. We show that participants’ reluctance to consider exceptions in legal reasoning depends on the modal auxiliary used. In two experiments we phrased legal conditionals either with the modal “should” (i.e., “ . . . then this person should be punished”), or with “will” (i.e., “ . . . then this person will be punished”) and presented them as modus ponens or modus tollens inferences. Participants had to decide whether the offender should or will be punished (modus ponens) or whether the offender indeed committed the offence (modus tollens). For modus ponens inferences phrased with “should” we replicate previous findings showing that participants select conclusions on the basis of their own sense of justice (Experiments 1 and 2). Yet, when the legal conditional is phrased with the modal “will” this effect is attenuated (Experiments 1 and 2), and exceptions are considered (Experiment 1). The modal auxiliary did not affect modus tollens inferences.     

Effect of a Single Session of a Yogic Meditation Technique on Cognitive Performance in Medical Students: A Randomized Crossover Trial

Medical students confront enormous academic, psychosocial, and existential stress throughout their training, leading to a cascade of consequences both physically and psychologically. The declined cognitive function of these students interferes in their academic performance and excellence. The purpose of this study was to examine the effectiveness of a yogic meditation technique, mind sound resonance technique (MSRT), on cognitive functions of University Medical students in a randomized, two-way crossover study. In total, 42 healthy volunteers of both genders (5 males and 37 females) with mean age of 19.44 ± 1.31 years were recruited from a medical college in South India, based on the inclusion and exclusion criteria. A 10-day orientation in the technique of MSRT was given to all the recruited subjects after which each subject underwent both MSRT and supine rest (SR) sessions. All participants were randomized in a 1:1 ratio to receive a session of either MSRT or SR. After a day of washout, participants crossed over to receive the alternative intervention. The cognitive functions were assessed using 2 paper-pencil tasks called Digit Letter Substitution Test (DLST) and Six-Letter Cancelation Task (SLCT), before and immediately after both sessions. Both the groups showed significant improvement in net attempt of both DLST and SLCT, but the magnitude of change was more in the MSRT group than in the SR group. The MSRT group demonstrated significantly enhanced net scores in both SLCT (p < 0.001) and DLST (p < 0.001). The result of the present study suggests that a single session of MSRT, a Mind–Body Practice, may positively impact the performance in cognitive tasks by the University Medical Students.     

Evoking false beliefs about autobiographical experience

In two experiments, we demonstrate that laboratory procedures can evoke false beliefs about autobiographical experience. After shallowly processing photographs ofreal-world locations, participants returned 1 week (Experiments 1 and 2) or 3 weeks (Experiment 2) later to evaluate whether they had actually visited each of a series of new and old pictured locations. Mundane and unique scenes from an unfamiliar college campus (Duke or SMU) were shown zero, one, or two times in the first session. Prior exposure increased participants' beliefs that they had visited locations that they had never actually visited. Furthermore, participants gave higher visit ratings to mundane than to unique scenes, and this did not vary with exposure frequency or delay. This laboratory procedure for inducing autobiographical false beliefs may have implications for better understanding various illusions of recognition.     

A Pilot Study Assessing the Effectiveness of Equine-Assisted Learning with Adolescents

This study contains an observation of six female participants (N = 6) who completed 8 weeks of a psychoeducational life skills program. The program included psychoeducational sessions that covered life skills related to partnership, respect, boundaries, communication, emotional regulation, problem-solving, and teamwork followed by an Equine-Assisted Learning (EAL) session. A paired sample t-test was conducted to measure the effectiveness of the equine therapy program with the psychoeducation lesson. A mental health professional, equine specialist, and a ranch worker observed and scored participants’ behaviors after each session. A paired-samples t-test was conducted after week 4 and week 7; the results indicated that participants showed improvement in communication, confidence, and respect scores. The participants demonstrated improvements with emotional regulation t(11) = 2.862, p = .015.     

Perceiving performer identity and intended expression intensity in point-light displays of dance

This study investigated agent and expression intensity recognition in point-light displays depicting dancing performances. In a first session, participants danced with two different expression intensities to music, solo or in dyads. In a subsequent session, they watched point-light displays of 1–5-s duration, depicting their own, their partner’s or another participant’s recorded actions, and were asked to identify the agent (self vs. partner vs. stranger) and the intended expression intensity (expressive vs. inexpressive) of the performer. The results indicate that performer identity and expression intensity could be discerned reliably from displays as short as 1 s. The accuracy in judgment increased with exposure duration and, for performer identification, with higher expression intensity. Judgment accuracy in agent and expression intensity recognition tasks correlated with self-report empathy indices. Accuracy correlated also with confidence in judgment, but only in the intensity recognition task. The results are discussed in relation to perceptual and neural mechanisms underlying action and intention recognition.     

Book review

In two experiments, participants were asked to perform simple action statements or to imagine performing the actions one, two, or four times in a single study session. The lag between repetitions could vary from 5 to 10 intervening items in Experiment 1 or be fixed at 0 and 4 in Experiment 2. In a test session that occurred either 24 or 48 hours later, participants were instructed to recognise statements only if they had occurred during the first session and, if recognised, to tell whether the action statement had been carried out or imagined. The primary finding was that it is possible to obtain an imagination inflation effect (that is, as repeated imaginations increase, participants are more likely to remember an action as performed) using a within-list paradigm. However, this outcome occurred only for spaced repetitions. The results are consistent with the hypothesis that repeated imagination increases the level of familiarity, which may, in turn, generate this memory illusion.     

The relationship between online visual representation of a scene and long-term scene memory

In 3 experiments the author investigated the relationship between the online visual representation of natural scenes and long-term visual memory. In a change detection task, a target object either changed or remained the same from an initial image of a natural scene to a test image. Two types of changes were possible: rotation in depth, or replacement by another object from the same basic-level category. Change detection during online scene viewing was compared with change detection after delay of 1 trial (Experiments 2A and 2B) until the end of the study session (Experiment 1) or 24 hr (Experiment 3). There was little or no decline in change detection performance from online viewing to a delay of 1 trial or delay until the end of the session, and change detection remained well above chance after 24 hr. These results demonstrate that long-term memory for visual detail in a scene is robust.     

Age-of-acquisition effects in delayed picture-naming tasks

We report two experiments that explored the linguistic locus of age-of-acquisition effects in picture naming by using a delayed naming task that involved only a low proportion of trials (25 %) while, for the large majority of the trials (75 %), participants performed another task—that is, the prevalent task. The prevalent tasks were semantic categorization in Experiment 1a and grammatical-gender decision in Experiments 1b and 2. In Experiment 1a, in which participants were biased to retrieve semantic information in order to perform the semantic categorization task, delayed naming times were affected by age of acquisition, reflecting a postsemantic locus of the effect. In Experiments 1b and 2, in which participants were biased to retrieve lexical information in order to perform the grammatical gender decision task, there was also an age-of-acquisition effect. These results suggest that part of the age-of-acquisition effect in picture naming occurs at the level at which the phonological properties of words are retrieved.     

Reducing Academic Procrastination Through a Group Treatment Program: A Pilot Study

The present study assessed a short-term group treatment program using cognitive interventions focused on students’ procrastination. A structured 90-min session program was used with 10 students (5 female, 5 male; M _age = 21.8, SD = 3.2) across 5 weeks. In the first and last session of the program participants completed a two reliable and valid procrastination scales, and then 8 weeks later in the follow up sessions filled out the same questionnaires. During the group sessions, participants identified their irrational thoughts as well as cognitive distortions associated with their procrastination tendencies. Results of a non-parametric Friedman Test revealed a significant decrease in participants’ academic procrastination score and general procrastination scores from the pre-test to follow-up test suggesting that the program was deemed to be successful.     

Memory for actions: Self-performed tasks and the reenactment effect

Encoding action phrases by enactment (self-performed tasks, or SPTs) leads to better memory than does observing actions (experimenter-performed tasks, or EPTs) or hearing action phrases (Engelkamp, 1998). In addition, recognition memory for SPTs is enhanced when test items are reenacted. Experiment 1 demonstrated a reenactment effect for EPTs, as well as for SPTs, indicating that the effect can be based on visual, as well as motoric, feedback. However, the reenactment effect in SPTs was found even when the participants were blindfolded at test (Experiment 2), indicating that the basis for the reenactment effect differs across SPTs and EPTs. Experiments 3 and 4 provided additional evidence that visual feedback is not critical for reenactment recognition in the case of SPTs. In addition, these experiments failed to show a hand congruency effect (enhanced recognition when the same hand enacts at study and at test), indicating that this effect is not as generalizable as the reenactment effect. These results have important implications for the motor-encoding hypothesis of the enactment effect.     

Text–Picture Integration: How Delayed Testing Moderates Recognition of Pictorial Information in Multimedia Learning

When learning with multimedia, text and pictures are assumed to be integrated with each other. Arndt, Schüler, and Scheiter (Learning & Instruction, 35, 62–72, 2015) confirmed the process of text picture integration for sentence recognition, not, however, for picture recognition. The current paper investigates the underlying reasons for the latter finding. Two experiments are reported, where subjects memorized text–picture stimuli that differed in the specificity of information contained in either sentences or pictures. In a subsequent picture recognition test, subjects showed no integration effect after a 30‐minute delay (Experiments 1 and 2), but only after a 1‐week delay (Experiment 2). Furthermore, eye‐tracking data showed that participants sufficiently processed the pictures during learning (Experiment 1). This data pattern speaks in favor of the assumption that after a short delay participants had available a short‐lived pictorial surface representation, which masked the integration effect for pictorial recognition.Copyright © 2015 John Wiley & Sons, Ltd.     

Manipulating perception versus action in recalibration tasks

We conducted six experiments to examine how manipulating perception versus action affects perception–action recalibration in real and imagined blindfolded walking tasks. Participants first performed a distance estimation task (pretest) and then walked through an immersive virtual environment on a treadmill for 10 min. Participants then repeated the distance estimation task (posttest), the results of which were compared with their pretest performance. In Experiments 1a, 2a, and 3a, participants walked at a normal speed during recalibration, but the rate of visual motion was either twice as fast or half as fast as the participants' walking speed. In Experiments 1b, 2b, and 3b, the rate of visual motion was kept constant, but participants walked at either a faster or a slower speed. During pre- and posttest, we used either a blindfolded walking distance estimation task or an imagined walking distance estimation task. Additionally, participants performed the pretest and posttest distance estimation tasks in either the real environment or the virtual environment. With blindfolded walking as the distance estimation task for pre- and posttest, we found a recalibration effect when either the rate of visual motion or the walking speed was manipulated during the recalibration phase. With imagined walking as the distance estimation task, we found a recalibration effect when the rate of visual motion was manipulated, but not when the walking speed was manipulated in both the real environment and the virtual environment. Discussion focuses on how spatial-updating processes operate on perception and action and on representation and action.     

The benefits of self-forgiveness on mental health: Evidence from correlational and experimental research

Previous research on self-forgiveness is mixed. Some argue self-forgiveness may have a salutary influence on mental health problems following an offense, whereas others suggest it may provide an excuse to reoffend. In two studies, we provide correlational and experimental evidence for the salutary effects of self-forgiveness following an offense. In Study 1 (N = 100), self-forgiveness was associated with lower levels of disordered eating behavior. In Study 2 (N = 462), participants recalled a drinking-related transgression, and were randomly assigned to a self-forgiveness or neutral priming condition. Results revealed that participants in the self-forgiveness condition reported significantly more self-forgiving beliefs and fewer feelings of remorse and self-condemnation than participants in the neutral priming condition to the degree that participants believed their drinking was the cause of the offense. These findings highlight the salutary effects of self-forgiveness.     

Timing matters: Temporal dynamics of stress effects on memory retrieval

Stress may impair memory retrieval. This retrieval impairment has been attributed to the action of the stress hormone cortisol, which is released with a delay of several minutes after a stressful encounter. Hence, most studies tested memory retrieval 20–30 min after stress, when the stress-induced cortisol increase peaks. In the present experiment, we investigated whether retrieval impairments can also be found at later intervals after stress. To this end, participants learned a list of words on day 1. Twenty-four hours later, they were first exposed to a stressor or a nonstressful control manipulation and completed a recognition test for the words either immediately thereafter, 25 min later, or 90 min later. Our findings showed that stress did not impair memory retrieval when memory was tested immediately after the stressor, before cortisol levels were elevated. However, retrieval performance was impaired 25 min after stress, when cortisol levels peaked, as well as 90 min after the stressor, when cortisol levels had already returned to baseline. The retrieval impairment 90 min after stress appeared to be even stronger than the one after 25 min. These findings suggest that the detrimental effects of stress on retrieval performance may last longer than is usually assumed.     

Recognizing familiar objects by hand and foot: Haptic shape perception generalizes to inputs from unusual locations and untrained body parts

The limits of generalization of our 3-D shape recognition system to identifying objects by touch was investigated by testing exploration at unusual locations and using untrained effectors. In Experiments 1 and 2, people found identification by hand of real objects, plastic 3-D models of objects, and raised line drawings placed in front of themselves no easier than when exploration was behind their back. Experiment 3 compared one-handed, two-handed, one-footed, and two-footed haptic object recognition of familiar objects. Recognition by foot was slower (7 vs. 13 s) and much less accurate (9 % vs. 47 % errors) than recognition by either one or both hands. Nevertheless, item difficulty was similar across hand and foot exploration, and there was a strong correlation between an individual’s hand and foot performance. Furthermore, foot recognition was better with the largest 20 of the 80 items (32 % errors), suggesting that physical limitations hampered exploration by foot. Thus, object recognition by hand generalized efficiently across the spatial location of stimuli, while object recognition by foot seemed surprisingly good given that no prior training was provided. Active touch (haptics) thus efficiently extracts 3-D shape information and accesses stored representations of familiar objects from novel modes of input.
