Brain Injury & Reading a Clock — It’s About Time

Checking the time is firmly established in our behavior. Whether checking your watch, reading a clock on the wall, or looking at the time on your computer or phone, you’ve likely checked the time within the last few minutes. It’s habitual.

“Clock reading” and “clock math” are extremely functional and important skills. They help us to be oriented to the time of day, when to wake up or go to bed, when to follow our routine, what commitments we have that day, and how much time these commitments will take.

For many, clock skills are taken for granted; however, challenges with clock reading and time-based math affects individuals across their lifespan. For example, one study found that children who have mathematical difficulties also demonstrate increased challenges in clock reading (Burney et al, 2011). Additionally, other studies found that clock reading and everyday numerical skills are affected in individuals with dementia (Schmidtke & Olbrich, 2007; Martini et al, 2003).

Problems Telling Time and Time-Based Calculations as a Result of an Injury

Difficulties reading clocks and time calculations can also occur as a result of a stroke, traumatic brain injury, or other neurological disorders. It can be affected by different types of impairments including visual processing, spatial neglect, cognitive, and/or language processing.

Are you in search for functional therapy activities for adults or children? Today, we will be featuring two tasks from our Everyday Skills category: Clock Reading and Clock Math.

Why are Clock Reading and Clock Math Important?

Clock tasks are among the functional activities for adults in speech therapy and occupational therapy because it uses a common activity to target a variety of goals. In terms of cognition, It targets cognitive processes including: attention, memory, visuospatial skills, mathematical functions, reasoning, and executive functioning.

While clock tasks are often thought to be a more of a cognitive speech therapy activity for adults, language processes also play a role. Numerical representations are mapped to meanings stored in your brain. Based on the configuration on the clock, your brain must convert this to a word in your head and then map this word to a meaning in your brain. These tasks are also functional for adults with aphasia.

Featured Task: Clock Reading

What is Clock Reading?

Your client is presented with an analog clock and three multiple choice questions. Your client must accurately read the clock and match to its corresponding written time.

How is Clock Reading Leveled?

There are 2 levels, with the multiple choice dis tractors become increasingly more similar as level difficulty increases.

How is Clock Reading Scored?

Scoring is binary (response is either correct or incorrect). The client has the opportunity to review response before moving on to the next item. Overall score is based on the % correct items given.

Featured Task: Clock Math

What is Clock Math?

Your client is presented with an analog clock and three multiple choice questions. Your client must accurately read the clock, and perform a mathematical calculation to determine how much time has elapsed.

How is Clock Math Leveled?

There are 3 levels:

  • Level 1: Clock displays times only to the quarter hour
  • Level 2: Clock displays times outside of the quarter hour
  • Level 3: Clock displays times outside of the quarter hour with more similar multiple choice distractors
How is Clock Math Scored?

Scoring is binary (response is either correct or incorrect). The client has the opportunity to review response before moving on to the next item. Overall score is based on the % correct items given.

Functional Therapy Activities in Speech Therapy and Occupational Therapy

How can Clock Reading and Clock Math be used in therapy? These tasks are extremely functional therapy activities for adults and children because it targets activities of daily living and a variety of skill areas.

Examples of how clock tasks can be used in therapy sessions:

  • Unilateral Left Neglect or Left Inattention: Train scanning strategies.
  • Language Skills: For people with aphasia, clock tasks can be a functional language activity to improve reading comprehension of numbers during activities of daily living (ADLs).
  • Executive Functioning Skills: For clock reading, sequence the steps required to accurately tell time. For clock math, sequence the steps to solving the mathematical equation. Self-monitor for accurate responses prior to checking answers.
  • Memory: This can be a functional memory task in speech or occupational therapy. Clients can practice internal memory strategies such as rehearsal as they determine the time and match it to the correct answer or complete calculations in their head.
  • Reasoning: Clock math is a functional cognitive activity that can be applied to several problem-solving scenarios (e.g. how much time elapsed after an appointment).
  • Processing Speed: You and your client can monitor processing speed with Constant Therapy’s data and analytics. With both accuracy and latency scores available immediately upon response, this can provide helpful feedback to the client about how processing speed is improving in functional cognitive tasks.
