Chapter 12: New Significance and Identity: A Practical Theological Perspective

SUMMARY

This article looks at personal worth and identity, dependence, time and experience, change and loss, death, work and leisure from a distinctively Christian point of view that frees us from the distortions and dread of aging. We are called to embrace life as new creations through the years.     

Intrusive thoughts in patients with obsessive compulsive disorder and non-clinical participants: a comparison using the International Intrusive Thought Interview Schedule

The International Intrusive Thought Interview Schedule (IITIS) was used to assess and compare the unwanted intrusive thoughts (UITs) reported in a group of patients with obsessive compulsive disorder (OCD) and a non-clinical group. Although all participants reported at least one type of intrusion, OCD patients experienced more intrusive thoughts than non-clinical participants, and this difference was statistically significant. In the OCD group, intrusive thoughts were more frequent, interfered more with daily life, were considered to be more important to get out of the mind, and were more difficult to stop than in non-clinical participants. The two groups did not differ significantly in terms of five appraisals of the most distressing intrusive thought. One appraisal (importance) was used far more by the OCD group than the non-clinical group. For three appraisals (intolerance of anxiety, need to control, and intolerance of uncertainty), the difference was smaller. Only two of the strategies for controlling the most upsetting intrusive thought (ritual and avoidance) were of value in differentiating between the two groups. The IITIS (an instrument used to assess intrusions in non-clinical samples) appears to be of value for the assessment of patients with OCD.     

Gender differences in emotional experiences across childhood,romantic relationship,and self-defining memories

The aim of the present study is to examine the gender differences in emotional experiences across three different types of autobiographical memory. A total of 612 undergraduate students from Izmir, Turkey, were asked to recall a memory either from childhood, from romantic relationships, or from self-defining experiences. A gender difference was found in the intensity of anxiety, sadness, and pride for romantic relationship memories. Men had higher scores on emotional distancing than women in self-defining memories. With regard to emotional valance, women’s feelings were less positive than men’s feelings when remembering childhood and romantic relationship experiences, whereas they were more positive than men’s feelings when remembering self-defining experiences. The findings support the notion that gender differences in emotional experiences during the autobiographical recollection of personal life events vary across different memory types.     

Are children’s memory illusions created differently from those of adults? Evidence from levels-of-processing and divided attention paradigms

In two experiments, we investigated the robustness and automaticity of adults’ and children’s generation of false memories by using a levels-of-processing paradigm (Experiment 1) and a divided attention paradigm (Experiment 2). The first experiment revealed that when information was encoded at a shallow level, true recognition rates decreased for all ages. For false recognition, when information was encoded on a shallow level, we found a different pattern for young children compared with that for older children and adults. False recognition rates were related to the overall amount of correctly remembered information for 7-year-olds, whereas no such association was found for the other age groups. In the second experiment, divided attention decreased true recognition for all ages. In contrast, children’s (7- and 11-year-olds) false recognition rates were again dependent on the overall amount of correctly remembered information, whereas adults’ false recognition was left unaffected. Overall, children’s false recognition rates changed when levels of processing or divided attention was manipulated in comparison with adults. Together, these results suggest that there may be both quantitative and qualitative changes in false memory rates with age.     

Effects of test sequence on anterograde and retrograde impairment of negative emotional scenes1

Abstract: The present study examined recognition for sequences of scenes depicting emotional compared with neutral events. In two experiments, participants were presented with a thematic series of 18 slides of scenes in which the content of two critical scenes in the middle of the series were either emotional (dead men's bodies) or neutral (an opera). A two‐item, forced‐choice recognition paradigm was used to test participants’ immediate memory performance of all 18 slides of scenes. In Experiment 1, anterograde and retrograde amnesic effects were observed for the emotional, but not the neutral scenes when a test sequence of scenes was used that did not match the original presentation order. In contrast, in Experiment 2 the test sequence matched the order seen during the original presentation, and both the anterograde and retrograde amnesic effects were not found. These results indicate that the reinstatement of the original event context is an important factor for the recognition of negative emotional memories.     

Thirty-five-month-old children have spontaneous memories despite change of context for retrieval

ABSTRACT

Many parents have experienced incidents in which their preschool child spontaneously (i.e., without prompting of any kind) recall a previously experienced event. Until recently, such spontaneous memories had only been examined in non-controlled settings (e.g., diary studies). Using a novel experimental paradigm, a previous study has shown that when young children are brought back to a highly distinct setting (same room, same experimenter, same furnishing), in which they previously experienced an interesting event (a Teddy or a Game event), spontaneous memories can be triggered. However, exactly which cues (or combination of cues) are effective for the children’s memory, remains unknown. Here, we used this novel paradigm to examine the possible impact of contextual cues at the time of retrieval. We manipulated whether the 35-month-old children returned to the same room (n?=?40) or to a different, but similarly furnished, room (n?=?40) after one week. The results revealed that although the children returning to a new room produced fewer spontaneous memories than the children returning to the same room, the difference was not significant. Interestingly, despite changing rooms, the children still produced spontaneous memories. Taken together the results may shed new light on the mechanisms underlying childhood amnesia.     

The use of safety behaviours to manage intrusive memories in depression

Cognitive models of clinical disorders conceptualise cognitive and behavioural safety-seeking behaviours as central to symptom persistence because they prevent disconfirmation of key maintaining beliefs. Despite growing evidence of the role of negative beliefs about intrusive memories in depression, it remains unclear why such beliefs persist. Accordingly, we examined whether safety behaviours in response to unhelpful beliefs about intrusive memories might play a role in their maintenance. Eighteen high dysphoric (i.e., BDI-II12) individuals who reported an intrusive negative autobiographical memory in the past week completed a battery of measures about their memory, associated negative beliefs and safety behaviours adopted in response to their beliefs. The most commonly endorsed beliefs reflected themes of wanting to control memories (e.g., ‘I should be able to rid my mind of this memory’) and self-deprecation about experiencing them (e.g., ‘Because I can’t control this memory, I am a weak person’). The beliefs prompted a range of safety behaviours, with cognitive distraction being the most common. The findings demonstrate that safety behaviours are common in response to maladaptive beliefs about intrusive memories. Treatment developments in this area are needed, and should incorporate strategies to challenge beliefs about memories, reduce the use of safety behaviours, and promote processing of intrusive memories.

Geometric analogue of holographic reduced representation

Holographic reduced representations (HRRs) are distributed representations of cognitive structures based on superpositions of convolution-bound n-tuples. Restricting HRRs to n-tuples consisting of ±1, one reinterprets the variable binding as a representation of the additive group of binary n-tuples with addition modulo 2. Since convolutions are not defined for vectors, the HRRs cannot be directly associated with geometric structures. Geometric analogues of HRRs are obtained if one considers a projective representation of the same group in the space of blades (geometric products of basis vectors) associated with an arbitrary n-dimensional Euclidean (or pseudo-Euclidean) space. Switching to matrix representations of Clifford algebras, one can always turn a geometric analogue of an HRR into a form of matrix distributed representation. In typical applications the resulting matrices are sparse, so that the matrix representation is less efficient than the representation directly employing the rules of geometric algebra. A yet more efficient procedure is based on ‘projected products’, a hierarchy of geometrically meaningful n-tuple multiplication rules obtained by combining geometric products with projections on relevant multivector subspaces. In terms of dimensionality the geometric analogues of HRRs are in between holographic and tensor-product representations.     

Implicit and explicit appraisals of the importance of intrusive thoughts

To evaluate cognitive theories of obsessions, the current study experimentally manipulated appraisals of the importance of intrusive thoughts. Undergraduate students (N = 156) completed measures of obsessive-compulsive disorder (OCD) symptoms and beliefs and were primed with a list of commonly reported unwanted thoughts. Participants were then informed that unwanted thoughts are either (1) significant and indicative of their personal values, or (2) meaningless, or participants (3) received no instructions about unwanted thoughts. Participants then completed implicit and explicit measures of self-evaluation and interpretations of their unwanted thoughts. Results indicated that the manipulation shifted implicit appraisals of unwanted thoughts in the expected direction, but not self-evaluations of morality or dangerousness. Interestingly, explicit self-esteem and beliefs about the significance of unwanted thoughts were associated with measures of OCD beliefs, whereas implicit self-evaluations of dangerousness were better predicted by the interaction of pre-existing OCD beliefs with the manipulation. Results are discussed in terms of divergent predictors of implicit and explicit responses to unwanted thoughts.
