Description
Recognition memory tests are pivotal in the examination of episodic memory. The paradigm commonly utilizes two primary testing formats: the yes/no and forced-choice tests. The yes/no paradigm typically involves participants being presented with a series of stimuli and later asked whether each stimulus was previously encountered (yes) or not (no). The forced-choice paradigm presents participants with pairs of stimuli, requiring them to select the stimulus that was previously encountered among distractors.
The literature suggests that yes/no recognition tests rely more on recollection compared to forced-choice tests, and that the hippocampus plays a selective role in supporting the recollection process. Individuals with Down syndrome (DS) often exhibit deficits in episodic memory, which are hippocamal related. The study examined recognition memory using yes-no and forced-choice procedures in children and adolescents with DS and typical developing controls (TD) in order to determine whether the recognition memory deficit in DS was dependent upon the type of recognition test used. We employed two distinct testing methodologies and the same stimulus materials (includin both verbal and non verbal items). The performance of 14 individuals with DS (mean chronological age = 14.5 years) was compared to that of 22 TD controls (mean chronological age = 6 years). Results revealed impairments in both recognition memory tasks in children with DS, indicating difficulties in discriminating between familiar and novel stimuli. Understanding the specific nature of episodic memory deficits can provide valuable insights into the underlying neurobiological mechanisms and interventions tailored to enhance episodic memory in individuals with DS.
