How do forewarnings and post-warnings affect misinformation reliance? The impact of warnings on the continued influence effect and belief regression.

People often continue to rely on certain information in their reasoning, even if this information has been retracted; this is called the continued influence effect (CIE) of misinformation. One technique for reducing this effect involves explicitly warning people that there is a possibility that they might have been misled. The present study aimed to investigate these warnings' effectiveness, depending on when they were given (either before or after misinformation). In two experiments (N = 337), we found that while a forewarning did reduce reliance on misinformation, retrospectively warned participants (when the warning was placed either between the misinformation and the retraction or just before testing) relied on the misinformation to a similar degree as unwarned participants. However, the protective effect of the forewarning was not durable, as shown by the fact that reliance on the misinformation increased for over 7 days following the first testing, despite continued memory of the retraction.

Protecting against misinformation: Evaluating the effectiveness of three techniques to reduce memory conformity.

The memory conformity effect occurs when people witness a given incident (e.g. a crime) then talk to each other about it, and the statement of one person affects the memory account of the other person with respect to this incident. The aim of this article is to improve the quality of witness testimony by verifying the effectiveness of three methods that aim to reduce memory conformity effect: (1) an extended warning against misinformation; (2) a method based on information about memory functioning and its fallibility and (3) a method consisting in motivating participants to resist influence and demonstrating their individual vulnerability to it. In the presented experiment, the innovative MORI technique was used to study the memory conformity effect. This technique allows a pair of participants to sit beside each other, look at the same screen and see a different version of the same criminal event. In the next stages, the subjects are asked to answer a series of questions about different details, thereby introducing mutual misinformation; then, the participants perform an individual memory test. In the experimental conditions, this test was preceded by one of the three tested methods in each group, with the aim of determining their effectiveness in reducing memory conformity. It turns out that the implementation of an extended warning against misinformation eliminated the memory conformity effect, while the application of two other methods led to a reduction (but not complete elimination) of the studied phenomenon.

[Psychological gender in clinical depression. Preliminary study]. / Plec psychologiczna osób z depresja kliniczna doniesienia wstepne.

AIM: Psychosocial and social theories of mood disorders indicate that factors connected with women's gender roles could create a higher risk of depression. The fact that social role is an important factor associated with depressive disorders suggests that not only a biological but also a psychological gender influences the vulnerability to depression. METHOD: Gender schema theory was applied to investigate a role of femininity in depressive disorders. It was predicted that patients who identify themselves with the traditional feminine gender role will be more depressed than androgynous and undifferentiated patients or individuals with high level of masculinity. Sixty one patients suffering from affective disorder participated in this research. The Polish adaptation of Bem Sex - Role Inventory and Beck Depression Inventory were used to investigate the association between psychological gender and symptoms of depression. RESULTS: The results indicated that there is a significant connection between the type of psychological gender and the level of depression. The highest level of depression was shown by undifferentiated patients, femininity was also found to be associated with a great number of depressive symptoms. These findings also suggest that androgynous individuals and patients with a high level of masculinity tend to be less depressed. CONCLUSIONS: Psychological gender is an important factor which interacts to create a higher depression risk in men and women.

Online misinformation can distort witnesses' memories. Analysis of co-witness discussions using an online version of the MORI-v technique.

Introduction: The memory conformity effect occurs when people witness a given incident and then talk to each other about it, and the statement of one person affects the memory account of another person with respect to that incident. The main objectives of this experiment were (1) to examine the effectiveness of a modified version of the MORI-v technique in inducing the memory conformity effect and (2) to investigate how the manner in which participants discuss the observed event influences the magnitude of this effect. In general, the modified online MORI-v technique consists of the following main elements: (1) original material, that is, two versions of a short film which are identical except for certain critical details; for example, in one version, a thief puts on a red cap, but in the other version it is black; (2) the collaborative recognition test, that is, a discussion about the original material which leads to mutual misinformation; and (3) an individual recognition test that checks the effect of the discussion on the memory account of the original material. Methods: A total of 72 participants (36 pairs) aged 18-54 took part in the research. Participants were tested using the online MORI-v technique: They were familiarized with the original material on their computers at home, and then they talked about it via a video communication app and completed an individual recognition test on their computers. Importantly, the discussions were recorded and analyzed in detail after the experimental session. Results and discussion: Using the online MORI-v technique, the effect of memory conformity was demonstrated, that is, in the individual recognition test, the proportion of correct answers to questions about discussed details (related to misinformation) was lower than the proportion of correct answers to questions about non-discussed details. It was also demonstrated that if one participant introduced misinformation during the discussion about a particular item and the other did not question it, the latter's answer to that item during the individual recognition test was most often incorrect. However, if one participant introduced misinformation during the discussion about an item and the other questioned it, the latter's answer about that item during the individual recognition test was most often correct.

Survey of Beliefs about Hypnosis among Students, Therapists, Followers of Paranormal Beliefs, and the General Public in Poland.

The aim of the present study is to examine beliefs about hypnosis in a Polish sample, with a focus on possible misconceptions. The research included groups with different backgrounds regarding hypnosis: 1st- and 5th-year psychology students, psychotherapists using hypnosis, people interested in paranormal phenomena, and people from the general population. The results demonstrated mild misconceptions about hypnosis and significant differences in beliefs about hypnosis between the aforementioned groups. Additionally, within a Polish sample, psychotherapists using hypnosis and 5th-year students' views were most similar in their current scientific knowledge about hypnosis, while the groups targeting individuals unexposed to hypnosis and followers of paranormal beliefs showed significantly more misconceptions.

Vaccination against misinformation: The inoculation technique reduces the continued influence effect.

The continued influence effect of misinformation (CIE) is a phenomenon in which certain information, although retracted and corrected, still has an impact on event reporting, reasoning, inference, and decisions. The main goal of this paper is to investigate to what extent this effect can be reduced using the procedure of inoculation and how it can be moderated by the reliability of corrections' sources. The results show that the reliability of corrections' sources did not affect their processing when participants were not inoculated. However, inoculated participants relied on misinformation less when the correction came from a highly credible source. For this source condition, as a result of inoculation, a significant increase in belief in retraction, as well as a decrease in belief in misinformation was also found. Contrary to previous reports, belief in misinformation rather than belief in retraction predicted reliance on misinformation. These findings are of both great practical importance as certain boundary conditions for inoculation efficiency have been discovered to reduce the impact of the continued influence of misinformation, and theoretical, as they provide insight into the mechanisms behind CIE. The results were interpreted in terms of existing CIE theories as well as within the remembering framework, which describes the conversion from memory traces to behavioral manifestations of memory.

Mediators and Moderators of Reinforced Self-Affirmation as a Method for Reducing the Memory Misinformation Effect.

The misinformation effect occurs when an eyewitness includes information in his or her account that is incongruent with the event he or she witnessed, and stems from being exposed to incorrect external sources. This is a serious threat to the quality of witness testimony and to the correctness of decisions reached by courts. However, few methods have been developed to reduce the vulnerability of witnesses to misinformation. This article presents such a method, namely, reinforced self-affirmation (RSA), which, by increasing memory confidence of witnesses, makes them less inclined to rely on external sources of information and more on their own memory. The effectiveness of this method was confirmed in three experiments. It was also found that memory confidence, but not general self-confidence, is a mediator of the impact of RSA on misinformation effect (ME), and that contingent self-esteem and feedback acceptance, but not sense of self-efficacy or general self-esteem, are moderators of this impact. It is concluded that RSA may be a promising basis for constructing methods, which can be used by forensic psychologists in real forensic settings.

Reducing interrogative suggestibility: The role of self-affirmation and positive feedback.

Interrogative suggestibility, as measured with Gudjonsson Suggestibility Scales, consists of an individual's tendency to yield to misleading questions (Yield) and to change answers after negative feedback (Shift). This study aimed to determine whether reinforced self-affirmation (RSA), a technique that aims to boost self-confidence in order to increase the tendency to rely on one's own memory instead of external cues, can reduce interrogative suggestibility. RSA consists of self-affirmation induced by means of writing down one's greatest achievements in life and of manipulated positive feedback. The efficacy of two kinds of positive feedback was explored. Shift was reduced by positive feedback relating both to memory and to the feeling that a person is very independent in their judgements, while only feedback related to memory reduced Yield. The results are discussed in terms of the different mechanisms underlying Yield and Shift. Inducing independence of judgements might not have been effective in the case of Yield because to some extent it taps opinions but not the quality of a cognitive process such as memory. An individual may believe in their own opinions and views but still be unsure about the quality of their own memory.

Inducing resistance to the misinformation effect by means of reinforced self-affirmation: The importance of positive feedback.

The misinformation effect is one of the major threats for the quality of witness testimony. It involves including of information that is inconsistent with the course of an event, and which originates from sources other than the event itself, into a witness's report of the event. In the present article research is presented aiming at reducing the tendency to rely on misinformation. After viewing a video clip, participants received a post-event narrative describing the events in the film which in the misled group included some incorrect information about the clip. They were then administered reinforced self-affirmation (RSA), a technique aiming at boosting self-confidence in order to increase the tendency to rely on own memory instead of external cues. This technique consists of self-affirmation by means of writing down one's greatest achievements in life and manipulated positive feedback. Feedback about memory, perception and independence of judgements was analyzed. All types of feedback effectively reduced the misinformation effect. Mediation analyzes confirmed that RSA operates via increased self-confidence or self-independence.

Age Moderates the Relationships between Family Functioning and Neck Pain/Disability.

This cross-sectional clinical study was designed to explore the relationships between family functioning, coping styles, and neck pain and neck disability. It was hypothesized that better family functioning and more effective coping styles would be associated with less pain and pain-related disability. It also was hypothesized that these relationships would be stronger in older people because they have fewer resources, more limited coping styles, and may depend more on their family for support. In this study, 88 women with chronic non-traumatic neck pain completed the Family Assessment Measure (FAM), Coping Inventory for Stressful Situations (CISS), Neck Disability Index (NDI), and a Visual-Analogue Scale (VAS) measuring the subjective intensity of neck pain. Zero-order and partial correlations and hierarchical stepwise regression were performed. CISS was not correlated with the NDI orVAS. Good family functioning was correlated with lower NDI and VAS scores. Age was found to moderate the relationship between the FAM and both NDI and VAS. This relationship was significant and positive in older patients, but non-significant in younger patients. It was concluded that better family functioning is associated with lower neck disability and pain intensity, especially in the case of older women suffering from non-traumatic neck pain.

The relationships between suggestibility, influenceability, and relaxability.

This research explores the relationships between relaxability and various aspects of suggestibility and influenceability. The Jacobson Progressive Muscle Relaxation procedure was used to induce relaxation. Tests of direct suggestibility, relating to the susceptibility of overt suggestions, and indirect suggestibility, referring to indirect hidden influence, as well as self-description questionnaires on suggestibility and the tendency to comply were used. Thayer's Activation-Deactivation Adjective Check List, measuring various kinds of activation and used as a pre- and posttest, determined the efficacy of the relaxation procedure. Indirect, direct, and self-measured suggestibility proved to be positively related to the ability to relax, measured by Thayer's subscales relating to emotions. Compliance was not related to relaxability. The results are discussed in terms of the aspects of relaxation training connected with suggestibility.

Psychometric validation of the authorized Polish version of the Neck Disability Index.

PURPOSE: Psychometric validation of the authorized Polish version of the Neck Disability Index (NDI). METHODS: Ninety-five patients with neck pain were enrolled. Reliability was assessed through Cronbach's alpha, split-half reliability, intra-class correlation (ICC) and agreement between measures with limits of agreement using the interval of 48 hours. Validity was determined by the Pearson correlation of the NDI with VAS. Responsiveness included mainly Pearson correlations of score changes on the NDI with the Global rating of change (GRC) scale. Minimal detectable change (MDC) and factor analysis were performed. The cut-point for the change, with its sensitivity and specificity, and the area under the curve were determined with the receiver operating characteristic (ROC) curve analysis. RESULTS: Cronbach's alpha and split-half reliability were satisfactory. The ICC was 0.99. Bland and Altman analysis indicated an acceptable agreement between the measures. The correlation between the NDI and VAS was 0.55. Responsiveness estimated by the correlations between change scores of the NDI and GRC was -0.73 and -0.56. The MDC was 5.96. Factor analyses demonstrated a two-factor structure. The cut-point for detecting a change was 6.5. The sensitivity was 90% and specificity was 81%. CONCLUSIONS: The Polish version of the NDI showed good psychometric properties. It can be used both in clinical and research practice. Implications for Rehabilitation The Polish version of the NDI, developed by MAPI Research Institute, was researched on a sample of 95 patients with neck pain. The psychometric properties of the adapted version of the NDI were satisfactory. The Polish version of the NDI proved to be useful in clinical practice as well as in research.

The role of selected variables in the diagnosis of cervical derangement syndromes.

BACKGROUND: The study analyzed correlations between selected variables in cervical derangement syndromes. MATERIAL AND METHODS: We analyzed data from 63 patients regarding pain (VAS, McGill Pain Questionnaire), mobility (CROM goniometer), dizziness, nausea, the duration of the current episode, and the number of previous episodes (history). Student's t and chi(2) tests and Pearson's r correlation were used. RESULTS: Overall pain intensity correlated positively with the indexes of the McGill Pain Questionnaire, the duration of the current episode, intensity of the proximal and distal symptoms and negatively with protraction or extension. Headache correlated positively with neck pain and negatively with retraction. Neck pain cor-related negatively with multiple cervical movements and positively with intensity of the distal symptoms. A positive relationship between shoulder and upper limb pain was observed. Patients with higher overall pain intensity or lower shoulder pain intensity experienced dizziness more often. The duration of the current episode correlated positively with the number of previous episodes, the frequency of nausea, limited extension and limited protraction. Nausea coexisted with dizziness and reduced protraction. The degree of flexion restriction correlated positively with the number of previous episodes. CONCLUSIONS: 1. Overall and proximal pain intensity, mobility of the cervical spine, the duration of the current episode and dizziness are useful in diagnosis of cervical derangement syndromes. 2. Intensity of the distal symptoms, the number of previous episodes and nausea should be particularly monitored.
